object KCLRecordProcessorFactory

Constructs IRecordProcessorFactory.

See https://github.com/aws/aws-sdk-java/blob/master/src/samples/AmazonKinesisApplication/SampleKinesisApplication.java http://docs.aws.amazon.com/kinesis/latest/dev/kinesis-record-processor-implementation-app-java.html

N.B. This only constructs IRecordProcessorFactory, if you want higher level entry point take a look at KCLWorkerRunner.

    Quick scala translation of KCL example.

    Quick scala translation of KCL example.

    Assumes we are mostly interested in specifying a record processing function, running with some number of retries and sharing some required shutdown behavior.

    All parameters except for processRecords have defaults.

    checkpointInterval

    how often to save checkpoint to dynamodb

    numRetries

    how many times to retry operation on exception before giving up

    initialize

    (ShardId) => Unit : additional code to execute when handler is initialized

    shutdown

    (ShardId, Checkpointer, ShutdownReason) => Unit : additional code to execute on shutdown

    initialRetryDelay

    the initial failed operation retry delay value, defaults to 10 seconds

    maxRetryDelay

    the maximum failed operation retry delay value, defaults to 3 minutes

    processRecords

    (ShardId, Records, Checkpointer) => Unit : Kinesis record handler
