Ahmed Hamdy updated FLINK-31872:
--------------------------------
Description:
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.
