Region.isServiceSupported(String)AddTagsToStreamResult addTagsToStream(AddTagsToStreamRequest addTagsToStreamRequest)
Adds or updates tags for the specified Kinesis data stream. Each stream can have up to 10 tags.
If tags have already been assigned to the stream, AddTagsToStream overwrites any existing tags that
correspond to the specified tag keys.
AddTagsToStream has a limit of five transactions per second per account.
addTagsToStreamRequest - Represents the input for AddTagsToStream.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.CreateStreamResult createStream(CreateStreamRequest createStreamRequest)
Creates a Kinesis data stream. A stream captures and transports data records that are continuously emitted from different data sources or producers. Scale-out within a stream is explicitly supported by means of shards, which are uniquely identified groups of data records in a stream.
You specify and control the number of shards that a stream is composed of. Each shard can support reads up to five transactions per second, up to a maximum data read total of 2 MB per second. Each shard can support writes up to 1,000 records per second, up to a maximum data write total of 1 MB per second. If the amount of data input increases or decreases, you can add or remove shards.
The stream name identifies the stream. The name is scoped to the AWS account used by the application. It is also scoped by AWS Region. That is, two streams in two different accounts can have the same name, and two streams in the same account, but in two different Regions, can have the same name.
CreateStream is an asynchronous operation. Upon receiving a CreateStream request,
Kinesis Data Streams immediately returns and sets the stream status to CREATING. After the stream is
created, Kinesis Data Streams sets the stream status to ACTIVE. You should perform read and write
operations only on an ACTIVE stream.
You receive a LimitExceededException when making a CreateStream request when you try to
do one of the following:
Have more than five streams in the CREATING state at any point in time.
Create more shards than are authorized for your account.
For the default shard limit for an AWS account, see Amazon Kinesis Data Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact AWS Support.
You can use DescribeStream to check the stream status, which is returned in
StreamStatus.
CreateStream has a limit of five transactions per second per account.
createStreamRequest - Represents the input for CreateStream.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.CreateStreamResult createStream(String streamName, Integer shardCount)
createStream(CreateStreamRequest)DecreaseStreamRetentionPeriodResult decreaseStreamRetentionPeriod(DecreaseStreamRetentionPeriodRequest decreaseStreamRetentionPeriodRequest)
Decreases the Kinesis data stream's retention period, which is the length of time data records are accessible after they are added to the stream. The minimum value of a stream's retention period is 24 hours.
This operation may result in lost data. For example, if the stream's retention period is 48 hours and is decreased to 24 hours, any data already in the stream that is older than 24 hours is inaccessible.
decreaseStreamRetentionPeriodRequest - Represents the input for DecreaseStreamRetentionPeriod.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.DeleteStreamResult deleteStream(DeleteStreamRequest deleteStreamRequest)
Deletes a Kinesis data stream and all its shards and data. You must shut down any applications that are operating
on the stream before you delete the stream. If an application attempts to operate on a deleted stream, it
receives the exception ResourceNotFoundException.
If the stream is in the ACTIVE state, you can delete it. After a DeleteStream request,
the specified stream is in the DELETING state until Kinesis Data Streams completes the deletion.
Note: Kinesis Data Streams might continue to accept data read and write operations, such as
PutRecord, PutRecords, and GetRecords, on a stream in the DELETING state until
the stream deletion is complete.
When you delete a stream, any shards in that stream are also deleted, and any tags are dissociated from the stream.
You can use the DescribeStream operation to check the state of the stream, which is returned in
StreamStatus.
DeleteStream has a limit of five transactions per second per account.
deleteStreamRequest - Represents the input for DeleteStream.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests

deleteStream(DeleteStreamRequest)DescribeLimitsResult describeLimits(DescribeLimitsRequest describeLimitsRequest)
Describes the shard limits and usage for the account.
If you update your account limits, the old limits might be returned for a few minutes.
This operation has a limit of one transaction per second per account.
describeLimitsRequest - LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.DescribeStreamResult describeStream(DescribeStreamRequest describeStreamRequest)
Describes the specified Kinesis data stream.
The information returned includes the stream name, Amazon Resource Name (ARN), creation time, enhanced metric configuration, and shard map. The shard map is an array of shard objects. For each shard object, there is the hash key and sequence number ranges that the shard spans, and the IDs of any earlier shards that played in a role in creating the shard. Every record ingested in the stream is identified by a sequence number, which is assigned when the record is put into the stream.
You can limit the number of shards returned by each call. For more information, see Retrieving Shards from a Stream in the Amazon Kinesis Data Streams Developer Guide.
There are no guarantees about the chronological order shards returned. To process shards in chronological order, use the ID of the parent shard to track the lineage to the oldest shard.
This operation has a limit of 10 transactions per second per account.

exceeds the maximum number allowed.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.GetRecordsResult getRecords(GetRecordsRequest getRecordsRequest)
Gets data records from a Kinesis data stream's shard.
Specify a shard iterator using the ShardIterator parameter. The shard iterator specifies the
position in the shard from which you want to start reading data records sequentially. If there are no records
available in the portion of the shard that the iterator points to, GetRecords returns an empty list. It
might take multiple calls to get to a portion of the shard that contains records.
You can scale by provisioning multiple shards per stream while considering service limits (for more information,
see Amazon Kinesis Data
Streams Limits in the Amazon Kinesis Data Streams Developer Guide). Your application should have one
thread per shard, each reading continuously from its stream. To read from a stream continually, call
GetRecords in a loop. Use GetShardIterator to get the shard iterator to specify in the first
GetRecords call. GetRecords returns a new shard iterator in NextShardIterator. Specify
the shard iterator returned in NextShardIterator in subsequent calls to GetRecords. If the
shard has been closed, the shard iterator can't return more data and GetRecords returns null
in NextShardIterator. You can terminate the loop when the shard is closed, or when the shard
iterator reaches the record with the sequence number or other attribute that marks it as the last record to
process.
Each data record can be up to 1 MB in size, and each shard can read up to 2 MB per second. You can ensure that
your calls don't exceed the maximum supported size or throughput by using the Limit parameter to
specify the maximum number of records that GetRecords can return. Consider your average record size when
determining this limit.
The size of the data returned by GetRecords varies depending on the utilization of the shard. The maximum
size of data that GetRecords can return is 10 MB. If a call returns this amount of data, subsequent calls
made within the next five seconds throw ProvisionedThroughputExceededException. If there is
insufficient provisioned throughput on the stream, subsequent calls made within the next one second throw
ProvisionedThroughputExceededException. GetRecords won't return any data when it throws an
exception. For this reason, we recommend that you wait one second between calls to GetRecords; however,
it's possible that the application will get exceptions for longer than 1 second.
To detect whether the application is falling behind in processing, you can use the
MillisBehindLatest response attribute. You can also monitor the stream using CloudWatch metrics and
other mechanisms (see Monitoring in
the Amazon Kinesis Data Streams Developer Guide).
Each Amazon Kinesis record includes a value, ApproximateArrivalTimestamp, that is set when a stream
successfully receives and stores a record. This is commonly referred to as a server-side time stamp, whereas a
client-side time stamp is set when a data producer creates or sends the record to a stream (a data producer is
any data source putting data records into a stream, for example with PutRecords). The time stamp has
millisecond precision. There are no guarantees about the time stamp accuracy, or that the time stamp is always
increasing. For example, records in a shard or across a stream might have time stamps that are out of order.
getRecordsRequest - Represents the input for GetRecords.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.ProvisionedThroughputExceededException - The request rate for the stream is too high, or the requested data is too large for the available
throughput. Reduce the frequency or size of your requests. For more information, see Streams Limits in
the Amazon Kinesis Data Streams Developer Guide, and Error Retries and Exponential
Backoff in AWS in the AWS General Reference.ExpiredIteratorException - The provided iterator exceeds the maximum age allowed.KMSDisabledException - The request was rejected because the specified customer master key (CMK) isn't enabled.KMSInvalidStateException - The request was rejected because the state of the specified resource isn't valid for this request. For
more information, see How
Key State Affects Use of a Customer Master Key in the AWS Key Management Service Developer
Guide.KMSAccessDeniedException - The ciphertext references a key that doesn't exist or that you don't have access to.KMSNotFoundException - The request was rejected because the specified entity or resource can't be found.KMSOptInRequiredException - The AWS access key ID needs a subscription for the service.KMSThrottlingException - The request was denied due to request throttling. For more information about throttling, see Limits in
the AWS Key Management Service Developer Guide.GetShardIteratorResult getShardIterator(GetShardIteratorRequest getShardIteratorRequest)
Gets an Amazon Kinesis shard iterator. A shard iterator expires five minutes after it is returned to the requester.
A shard iterator specifies the shard position from which to start reading data records sequentially. The position is specified using the sequence number of a data record in a shard. A sequence number is the identifier associated with every record ingested in the stream, and is assigned when a record is put into the stream. Each stream has one or more shards.
You must specify the shard iterator type. For example, you can set the ShardIteratorType parameter
to read exactly from the position denoted by a specific sequence number by using the
AT_SEQUENCE_NUMBER shard iterator type. Alternatively, the parameter can read right after the
sequence number by using the AFTER_SEQUENCE_NUMBER shard iterator type, using sequence numbers
returned by earlier calls to PutRecord, PutRecords, GetRecords, or DescribeStream. In
the request, you can specify the shard iterator type AT_TIMESTAMP to read records from an arbitrary
point in time, TRIM_HORIZON to cause ShardIterator to point to the last untrimmed
record in the shard in the system (the oldest data record in the shard), or LATEST so that you
always read the most recent data in the shard.
When you read repeatedly from a stream, use a GetShardIterator request to get the first shard iterator for
use in your first GetRecords request and for subsequent reads use the shard iterator returned by the
GetRecords request in NextShardIterator. A new shard iterator is returned by every
GetRecords request in NextShardIterator, which you use in the ShardIterator
parameter of the next GetRecords request.
If a GetShardIterator request is made too often, you receive a
ProvisionedThroughputExceededException. For more information about throughput limits, see
GetRecords, and Streams Limits in the
Amazon Kinesis Data Streams Developer Guide.
If the shard is closed, GetShardIterator returns a valid iterator for the last sequence number of the shard. A shard can be closed as a result of using SplitShard or MergeShards.
GetShardIterator has a limit of five transactions per second per account per open shard.
getShardIteratorRequest - Represents the input for GetShardIterator.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.ProvisionedThroughputExceededException - The request rate for the stream is too high, or the requested data is too large for the available
throughput. Reduce the frequency or size of your requests. For more information, see Streams Limits in
the Amazon Kinesis Data Streams Developer Guide, and Error Retries and Exponential
Backoff in AWS in the AWS General Reference.GetShardIteratorResult getShardIterator(String streamName, String shardId, String shardIteratorType)
GetShardIteratorResult getShardIterator(String streamName, String shardId, String shardIteratorType, String startingSequenceNumber)
IncreaseStreamRetentionPeriodResult increaseStreamRetentionPeriod(IncreaseStreamRetentionPeriodRequest increaseStreamRetentionPeriodRequest)
Increases the Kinesis data stream's retention period, which is the length of time data records are accessible after they are added to the stream. The maximum value of a stream's retention period is 168 hours (7 days).
If you choose a longer stream retention period, this operation increases the time period during which records that have not yet expired are accessible. However, it does not make previous, expired data (older than the stream's previous retention period) accessible after the operation has been called. For example, if a stream's retention period is set to 24 hours and is increased to 168 hours, any data that is older than 24 hours remains inaccessible to consumer applications.
increaseStreamRetentionPeriodRequest - Represents the input for IncreaseStreamRetentionPeriod.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.ListShardsResult listShards(ListShardsRequest listShardsRequest)
Lists the shards in a stream and provides information about each shard.
This API is a new operation that is used by the Amazon Kinesis Client Library (KCL). If you have a fine-grained IAM policy that only allows specific operations, you must update your policy to allow calls to this API. For more information, see Controlling Access to Amazon Kinesis Data Streams Resources Using IAM.
listShardsRequest - ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.ExpiredNextTokenException - The pagination token passed to the ListShards operation is expired. For more information,
see ListShardsInput$NextToken.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.ListStreamsResult listStreams(ListStreamsRequest listStreamsRequest)
Lists your Kinesis data streams.
The number of streams may be too large to return from a single call to ListStreams. You can limit
the number of returned streams using the Limit parameter. If you do not specify a value for the
Limit parameter, Kinesis Data Streams uses the default limit, which is currently 10.
You can detect if there are more streams available to list by using the HasMoreStreams flag from the
returned output. If there are more streams available, you can request more streams by using the name of the last
stream returned by the ListStreams request in the ExclusiveStartStreamName parameter in
a subsequent request to ListStreams. The group of stream names returned by the subsequent request is
then added to the list. You can continue this process until all the stream names have been collected in the list.
ListStreams has a limit of five transactions per second per account.
listStreamsRequest - Represents the input for ListStreams.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.ListStreamsResult listStreams()

listStreams(ListStreamsRequest)ListTagsForStreamResult listTagsForStream(ListTagsForStreamRequest listTagsForStreamRequest)
Lists the tags for the specified Kinesis data stream. This operation has a limit of five transactions per second per account.
listTagsForStreamRequest - Represents the input for ListTagsForStream.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.MergeShardsResult mergeShards(MergeShardsRequest mergeShardsRequest)
Merges two adjacent shards in a Kinesis data stream and combines them into a single shard to reduce the stream's capacity to ingest and transport data. Two shards are considered adjacent if the union of the hash key ranges for the two shards form a contiguous set with no gaps. For example, if you have two shards, one with a hash key range of 276...381 and the other with a hash key range of 382...454, then you could merge these two shards into a single shard that would have a hash key range of 276...454. After the merge, the single child shard receives data for all hash key values covered by the two parent shards.
MergeShards is called when there is a need to reduce the overall capacity of a stream because of
excess capacity that is not being used. You must specify the shard to be merged and the adjacent shard for a
stream. For more information about merging shards, see Merge Two
Shards in the Amazon Kinesis Data Streams Developer Guide.
If the stream is in the ACTIVE state, you can call MergeShards. If a stream is in the
CREATING, UPDATING, or DELETING state, MergeShards returns a
ResourceInUseException. If the specified stream does not exist, MergeShards returns a
ResourceNotFoundException.
You can use DescribeStream to check the state of the stream, which is returned in
StreamStatus.
MergeShards is an asynchronous operation. Upon receiving a MergeShards request, Amazon
Kinesis Data Streams immediately returns a response and sets the StreamStatus to
UPDATING. After the operation is completed, Kinesis Data Streams sets the StreamStatus
to ACTIVE. Read and write operations continue to work while the stream is in the
UPDATING state.
You use DescribeStream to determine the shard IDs that are specified in the MergeShards
request.
If you try to operate on too many streams in parallel using CreateStream, DeleteStream,
MergeShards, or SplitShard, you receive a LimitExceededException.
MergeShards has a limit of five transactions per second per account.

see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.MergeShardsResult mergeShards(String streamName, String shardToMerge, String adjacentShardToMerge)
mergeShards(MergeShardsRequest)PutRecordResult putRecord(PutRecordRequest putRecordRequest)
Writes a single data record into an Amazon Kinesis data stream. Call PutRecord to send data into the
stream for real-time ingestion and subsequent processing, one record at a time. Each shard can support writes up
to 1,000 records per second, up to a maximum data write total of 1 MB per second.
You must specify the name of the stream that captures, stores, and transports the data; a partition key; and the data blob itself.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams to distribute data across shards. Kinesis Data Streams segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine the shard to which a given data record belongs.
Partition keys are Unicode strings, with a maximum length limit of 256 characters for each key. An MD5 hash
function is used to map partition keys to 128-bit integer values and to map associated data records to shards
using the hash key ranges of the shards. You can override hashing the partition key to determine the shard by
explicitly specifying a hash value using the ExplicitHashKey parameter. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
PutRecord returns the shard ID of where the data record was placed and the sequence number that was
assigned to the data record.
Sequence numbers increase over time and are specific to a shard within a stream, not across all shards within a
stream. To guarantee strictly increasing ordering, write serially to a shard and use the
SequenceNumberForOrdering parameter. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
If a PutRecord request cannot be processed because of insufficient provisioned throughput on the
shard involved in the request, PutRecord throws ProvisionedThroughputExceededException.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

putRecord(PutRecordRequest)PutRecordResult putRecord(String streamName, ByteBuffer data, String partitionKey, String sequenceNumberForOrdering)
putRecord(PutRecordRequest)PutRecordsResult putRecords(PutRecordsRequest putRecordsRequest)
Writes multiple data records into a Kinesis data stream in a single call (also referred to as a
PutRecords request). Use this operation to send data into the stream for data ingestion and
processing.
Each PutRecords request can support up to 500 records. Each record in the request can be as large as
1 MB, up to a limit of 5 MB for the entire request, including partition keys. Each shard can support writes up to
1,000 records per second, up to a maximum data write total of 1 MB per second.
You must specify the name of the stream that captures, stores, and transports the data; and an array of request
Records, with each record in the array requiring a partition key and data blob. The record size
limit applies to the total size of the partition key and data blob.
The data blob can be any type of data; for example, a segment from a log file, geographic/location data, website clickstream data, and so on.
The partition key is used by Kinesis Data Streams as input to a hash function that maps the partition key and associated data to a specific shard. An MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream. For more information, see Adding Data to a Stream in the Amazon Kinesis Data Streams Developer Guide.
Each record in the Records array may include an optional parameter, ExplicitHashKey,
which overrides the partition key to shard mapping. This parameter allows a data producer to determine explicitly
the shard where the record is stored. For more information, see Adding Multiple Records with PutRecords in the Amazon Kinesis Data Streams Developer Guide.
The PutRecords response includes an array of response Records. Each record in the
response array directly correlates with a record in the request array using natural ordering, from the top to the
bottom of the request and response. The response Records array always includes the same number of
records as the request array.
The response Records array includes both successfully and unsuccessfully processed records. Kinesis
Data Streams attempts to process all records in each PutRecords request. A single record failure
does not stop the processing of subsequent records.
A successfully processed record includes ShardId and SequenceNumber values. The
ShardId parameter identifies the shard in the stream where the record is stored. The
SequenceNumber parameter is an identifier assigned to the put record, unique to all records in the
stream.
An unsuccessfully processed record includes ErrorCode and ErrorMessage values.
ErrorCode reflects the type of error and can be one of the following values:
ProvisionedThroughputExceededException or InternalFailure. ErrorMessage
provides more detailed information about the ProvisionedThroughputExceededException exception
including the account ID, stream name, and shard ID of the record that was throttled. For more information about
partially successful responses, see Adding Multiple Records with PutRecords in the Amazon Kinesis Data Streams Developer Guide.
By default, data records are accessible for 24 hours from the time that they are added to a stream. You can use IncreaseStreamRetentionPeriod or DecreaseStreamRetentionPeriod to modify this retention period.

Removes tags from the specified Kinesis data stream. Removed tags are deleted and cannot be recovered after this operation successfully completes.
If you specify a tag that does not exist, it is ignored.
RemoveTagsFromStream has a limit of five transactions per second per account.
removeTagsFromStreamRequest - Represents the input for RemoveTagsFromStream.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.SplitShardResult splitShard(SplitShardRequest splitShardRequest)
Splits a shard into two new shards in the Kinesis data stream, to increase the stream's capacity to ingest and
transport data. SplitShard is called when there is a need to increase the overall capacity of a
stream because of an expected increase in the volume of data records being ingested.
You can also use SplitShard when a shard appears to be approaching its maximum utilization; for
example, the producers sending data into the specific shard are suddenly sending more than previously
anticipated. You can also call SplitShard to increase stream capacity, so that more Kinesis Data
Streams applications can simultaneously read data from the stream for real-time processing.
You must specify the shard to be split and the new hash key, which is the position in the shard where the shard gets split in two. In many cases, the new hash key might be the average of the beginning and ending hash key, but it can be any hash key value in the range being mapped into the shard. For more information, see Split a Shard in the Amazon Kinesis Data Streams Developer Guide.
You can use DescribeStream to determine the shard ID and hash key values for the ShardToSplit
and NewStartingHashKey parameters that are specified in the SplitShard request.
SplitShard is an asynchronous operation. Upon receiving a SplitShard request, Kinesis
Data Streams immediately returns a response and sets the stream status to UPDATING. After the
operation is completed, Kinesis Data Streams sets the stream status to ACTIVE. Read and write
operations continue to work while the stream is in the UPDATING state.
You can use DescribeStream to check the status of the stream, which is returned in
StreamStatus. If the stream is in the ACTIVE state, you can call
SplitShard. If a stream is in CREATING or UPDATING or
DELETING states, DescribeStream returns a ResourceInUseException.
If the specified stream does not exist, DescribeStream returns a
ResourceNotFoundException. If you try to create more shards than are authorized for your account,
you receive a LimitExceededException.
For the default shard limit for an AWS account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To increase this limit, contact AWS Support.
If you try to operate on too many streams simultaneously using CreateStream, DeleteStream,
MergeShards, and/or SplitShard, you receive a LimitExceededException.
SplitShard has a limit of five transactions per second per account.

splitShard(SplitShardRequest)StartStreamEncryptionResult startStreamEncryption(StartStreamEncryptionRequest startStreamEncryptionRequest)
Enables or updates server-side encryption using an AWS KMS key for a specified stream.
Starting encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE. Updating or applying encryption normally
takes a few seconds to complete, but it can take minutes. You can continue to read and write data to your stream
while its status is UPDATING. Once the status of the stream is ACTIVE, encryption
begins for records written to the stream.
API Limits: You can successfully apply a new AWS KMS key for server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to five seconds after the stream is in an ACTIVE status before all records
written to the stream are encrypted. After you enable encryption, you can verify that encryption is applied by
inspecting the API response from PutRecord or PutRecords.
startStreamEncryptionRequest - InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the

For more information about throttling, see Limits in
the AWS Key Management Service Developer Guide.StopStreamEncryptionResult stopStreamEncryption(StopStreamEncryptionRequest stopStreamEncryptionRequest)
Disables server-side encryption for a specified stream.
Stopping encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE. Stopping encryption normally takes a few
seconds to complete, but it can take minutes. You can continue to read and write data to your stream while its
status is UPDATING. Once the status of the stream is ACTIVE, records written to the
stream are no longer encrypted by Kinesis Data Streams.
API Limits: You can successfully disable server-side encryption 25 times in a rolling 24-hour period.
Note: It can take up to five seconds after the stream is in an ACTIVE status before all records
written to the stream are no longer subject to encryption. After you disabled encryption, you can verify that
encryption is not applied by inspecting the API response from PutRecord or PutRecords.
stopStreamEncryptionRequest - InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
exceeds the maximum number allowed.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource must be in the
ACTIVE state.ResourceNotFoundException - The requested resource could not be found. The stream might not be specified correctly.UpdateShardCountResult updateShardCount(UpdateShardCountRequest updateShardCountRequest)
Updates the shard count of the specified stream to the specified number of shards.
Updating the shard count is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns
immediately and sets the status of the stream to UPDATING. After the update is complete, Kinesis
Data Streams sets the status of the stream back to ACTIVE. Depending on the size of the stream, the
scaling action could take a few minutes to complete. You can continue to read and write data to your stream while
its status is UPDATING.
To update the shard count, Kinesis Data Streams performs splits or merges on individual shards. This can cause short-lived shards to be created, in addition to the final shards. We recommend that you double or halve the shard count, as this results in the fewest number of splits or merges.
This operation has the following limits. You cannot do the following:
Scale more than twice per rolling 24-hour period per stream
Scale up to more than double your current shard count for a stream
Scale down below half your current shard count for a stream
Scale up to more than 500 shards in a stream
Scale a stream with more than 500 shards down unless the result is less than 500 shards
Scale up to more than the shard limit for your account
For the default limits for an AWS account, see Streams Limits in the Amazon Kinesis Data Streams Developer Guide. To request an increase in the call rate limit, the shard limit for this API, or your overall shard limit, use the limits form.
updateShardCountRequest - InvalidArgumentException - A specified parameter exceeds its restrictions, is not supported, or can't be used. For more information,
see the returned message.LimitExceededException - The requested resource exceeds the maximum number allowed, or the number of concurrent stream requests
