Abstract Value Members
- abstract def checkpointRecords(checkpointSettings: KinesisCheckpointSettings): Pipe[F, CommittableRecord, Record]
Pipe to checkpoint records in Kinesis, marking them as processed Groups records by shard id, so that each shard is subject to its own clustering of records After accumulating maxBatchSize or reaching maxBatchWait for a respective shard, the latest record is checkpointed By design, all records prior to the checkpointed record are also checkpointed in Kinesis

- checkpointSettings
configure maxBatchSize and maxBatchWait time before triggering a checkpoint
- returns
a stream of Record types representing checkpointed messages
- abstract def readFromDynamoDBStream(workerConfiguration: KinesisClientLibConfiguration): Stream[F, CommittableRecord]
Initialize a worker and start streaming records from a DynamoDB stream On stream finish (due to error or other), worker will be shutdown
Initialize a worker and start streaming records from a DynamoDB stream On stream finish (due to error or other), worker will be shutdown
- workerConfiguration
configuration parameters for the KCL
- returns
an infinite fs2 Stream that emits DynamoDB Records
- abstract def readFromDynamoDBStream(appName: String, streamName: String): Stream[F, CommittableRecord]
Initialize a worker and start streaming records from a DynamoDB stream On stream finish (due to error or other), worker will be shutdown
Initialize a worker and start streaming records from a DynamoDB stream On stream finish (due to error or other), worker will be shutdown
- appName
name of the DynamoDB application. Used by KCL when resharding
- streamName
name of the DynamoDB stream to consume from
- returns
an infinite fs2 Stream that emits Kinesis Records
