    Thank you for reviewing this @rmetzger. Should I address your comment after the rework
in https://github.com/apache/flink/pull/2131 is merged, and rebase this PR on that?

> Currently, the Kinesis consumer is calling getRecords() right after finishing previous
calls. This results in easily reaching Amazon's limitation of 5 GET requests per shard per
second. Although the code already has backoff & retry mechanism, this will affect other
applications consuming from the same Kinesis stream.
> Along with this new configuration and the already existing `KinesisConfigConstants.CONFIG_SHARD_RECORDS_PER_GET`,
users will have more control on the desired throughput behaviour for the Kinesis consumer.
