def checkpointRecords(checkpointSettings: KinesisCheckpointSettings): (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

Attributes

checkpointSettings

configure maxBatchSize and maxBatchWait time before triggering a checkpoint

Returns:

a stream of Record types representing checkpointed messages
