Makes sense, I'll remove it!
> Configurable idle time between getRecords requests to Kinesis shards

> Key: FLINK-4018
> URL: https://issues.apache.org/jira/browse/FLINK-4018
> Project: Flink
> Issue Type: Sub-task
> Components: Kinesis Connector, Streaming Connectors
> Affects Versions: 1.1.0
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Fix For: 1.1.0
>
>
> 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.
