Unknown exceptions will be thrown as an instance of this typedefault CreateStreamResponse createStream(CreateStreamRequest createStreamRequest) throws ResourceInUseException, LimitExceededException, InvalidArgumentException, SdkBaseException, SdkClientException, KinesisException
Creates an Amazon Kinesis 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 5 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. You can add shards to a stream if the amount of data input increases and you can remove shards if the amount of data input decreases.
The stream name identifies the stream. The name is scoped to the AWS account used by the application. It is also scoped by 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,
Amazon Kinesis immediately returns and sets the stream status to CREATING. After the stream is
created, Amazon Kinesis 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 if 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 Streams Limits in the Amazon Kinesis Streams Developer Guide. If you need 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 5 transactions per second per account.

Decreases the Amazon Kinesis 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.

Unknown exceptions will be thrown as an instance of this typedefault DeleteStreamResponse deleteStream(DeleteStreamRequest deleteStreamRequest) throws ResourceNotFoundException, LimitExceededException, SdkBaseException, SdkClientException, KinesisException
Deletes an Amazon Kinesis 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 will receive 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 Amazon Kinesis completes the deletion.
Note: Amazon Kinesis 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 5 transactions per second per account.
deleteStreamRequest - Represents the input for DeleteStream.ResourceNotFoundException - The requested resource could not be found.

Unknown exceptions will be thrown as an instance of this typedefault DescribeStreamResponse describeStream(DescribeStreamRequest describeStreamRequest) throws ResourceNotFoundException, LimitExceededException, SdkBaseException, SdkClientException, KinesisException
Describes the specified Amazon Kinesis 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 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.

Unknown exceptions will be thrown as an instance of this typedefault GetRecordsResponse getRecords(GetRecordsRequest getRecordsRequest) throws ResourceNotFoundException, InvalidArgumentException, ProvisionedThroughputExceededException, ExpiredIteratorException, SdkBaseException, SdkClientException, KinesisException
Gets data records from an Amazon Kinesis 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. Note
that 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 Streams Limits in
the Amazon Kinesis 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. Note that 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 5 seconds throw ProvisionedThroughputExceededException. If there is
insufficient provisioned throughput on the shard, subsequent calls made within the next 1 second throw
ProvisionedThroughputExceededException. Note that 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 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 timestamp, whereas a
client-side timestamp 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 timestamp has
millisecond precision. There are no guarantees about the timestamp accuracy, or that the timestamp is always
increasing. For example, records in a shard or across a stream might have timestamps 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 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.SdkBaseException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for

Unknown exceptions will be thrown as an instance of this typedefault GetShardIteratorResponse getShardIterator(GetShardIteratorRequest getShardIteratorRequest) throws ResourceNotFoundException, InvalidArgumentException, ProvisionedThroughputExceededException, SdkBaseException, SdkClientException, KinesisException
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, or 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 Streams Developer Guide.
If the shard is closed, GetShardIterator returns a valid iterator for the last sequence number of the shard. Note that a shard can be closed as a result of using SplitShard or MergeShards.
GetShardIterator has a limit of 5 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 Streams Developer Guide, and Error Retries and Exponential
Backoff in AWS in the AWS General Reference.SdkBaseException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for
catch all scenarios.SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc)KinesisException - Base exception for all service exceptions. Unknown exceptions will be thrown as an instance of this typedefault IncreaseStreamRetentionPeriodResponse increaseStreamRetentionPeriod(IncreaseStreamRetentionPeriodRequest increaseStreamRetentionPeriodRequest) throws ResourceInUseException, ResourceNotFoundException, InvalidArgumentException, SdkBaseException, SdkClientException, KinesisException
Increases the Amazon Kinesis 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).
Upon choosing a longer stream retention period, this operation will increase the time period records are accessible that have not yet expired. However, it will not make previous data that has expired (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 will remain inaccessible to consumer applications.
increaseStreamRetentionPeriodRequest - Represents the input for IncreaseStreamRetentionPeriod.ResourceInUseException - The resource is not available for this operation. For successful operation, the resource needs to be in

see the returned message.SdkBaseException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for

Unknown exceptions will be thrown as an instance of this typedefault ListStreamsResponse listStreams(ListStreamsRequest listStreamsRequest) throws LimitExceededException, SdkBaseException, SdkClientException, KinesisException
Lists your Amazon Kinesis 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, Amazon Kinesis 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 5 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

Unknown exceptions will be thrown as an instance of this typedefault MergeShardsResponse mergeShards(MergeShardsRequest mergeShardsRequest) throws ResourceNotFoundException, ResourceInUseException, InvalidArgumentException, LimitExceededException, SdkBaseException, SdkClientException, KinesisException
Merges two adjacent shards in an Amazon Kinesis 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 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 immediately returns a response and sets the StreamStatus to UPDATING. After the
operation is completed, Amazon Kinesis 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 will receive a LimitExceededException.
MergeShards has limit of 5 transactions per second per account.

Unknown exceptions will be thrown as an instance of this typedefault PutRecordResponse putRecord(PutRecordRequest putRecordRequest) throws ResourceNotFoundException, InvalidArgumentException, ProvisionedThroughputExceededException, SdkBaseException, SdkClientException, KinesisException
Writes a single data record into an Amazon Kinesis 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 Amazon Kinesis to distribute data across shards. Amazon Kinesis segregates the data records that belong to a stream into multiple shards, using the partition key associated with each data record to determine which shard a given data record belongs to.
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 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 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.
Data records are accessible for only 24 hours from the time that they are added to a stream.

Writes multiple data records into an Amazon Kinesis 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 Amazon Kinesis 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 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 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. Amazon
Kinesis 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 Streams Developer Guide.
By default, data records are accessible for only 24 hours from the time that they are added to an Amazon Kinesis stream. This retention period can be modified using the DecreaseStreamRetentionPeriod and IncreaseStreamRetentionPeriod operations.

Splits a shard into two new shards in the Amazon Kinesis 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 Amazon Kinesis
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 simply 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 about splitting shards, see Split a Shard in the Amazon Kinesis 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, Amazon
Kinesis immediately returns a response and sets the stream status to UPDATING. After the operation
is completed, Amazon Kinesis 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 Streams Developer Guide. If you need 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 limit of 5 transactions per second per account.

Unknown exceptions will be thrown as an instance of this typedefault UpdateShardCountResponse updateShardCount(UpdateShardCountRequest updateShardCountRequest) throws InvalidArgumentException, LimitExceededException, ResourceInUseException, ResourceNotFoundException, SdkBaseException, SdkClientException, KinesisException
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, Amazon Kinesis returns
immediately and sets the status of the stream to UPDATING. After the update is complete, Amazon
Kinesis 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, Amazon Kinesis performs splits and merges and 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 a rate limit of twice per rolling 24 hour period. You cannot scale above double your current shard count, scale below half your current shard count, or exceed the shard limits for your account.
For the default limits for an AWS account, see Streams Limits in the Amazon Kinesis Streams Developer Guide. If you need to increase a limit, contact AWS Support.
