Danny Cranmer updated FLINK-31872: ---------------------------------- Fix Version/s: aws-connector-4.3.0 (was: aws-connector-4.2.0) > Add Support for Configuring AIMD Ratelimiting strategy parameters by Sink > users for KinesisStreamsSink > ------------------------------------------------------------------------------------------------------ > > Key: FLINK-31872 > URL: https://issues.apache.org/jira/browse/FLINK-31872 > Project: Flink > Issue Type: Improvement > Components: Connectors / Kinesis > Reporter: Ahmed Hamdy > Assignee: Ahmed Hamdy > Priority: Major > Fix For: aws-connector-4.3.0 > > > 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.
