> h1. Issue
> As part of FLINK-31772
> I performed a complete benchmark for {{KinesisStreamsSink}} after configuring
> rate limiting strategy.
> It appears that optimum values for rate limiting strategy parameters are
> dependent on use case (shard number/ parallellism/ record thouroughput)
> We initially implemeted the {{AIMDRateLimitingStrategy}} in accordance with
> one used for TCP congestion control but since parameters are use case
> dependent we would like to allow sink users to adjust parameters as suitable.
> h2. Requirements
> - we *must* allow users to configure increment rate and decrease factor of
> AIMDRateLimitingStrategy for {{KinesisStreamsSink}}
> - we *must* provide backward compatible default values identical to current
> values to introduce no further regressions.
> h2. Appendix
> h3. Performace Benchmark Results
