> h1. Issue
> While benchmarking the {{KinesisStreamSink}} for 1.15 against the legacy {{FlinkKinesisProduced}} , it is observed that the new sink has a performance regression against the deprecated sink for same environment setting.
> Further investigation identified that the AIMD Ratelimiting strategy is the bottleneck for the regression.
> Attached results for {{KinesisStreamSink}} against {FlinkKinesisProducer} and {KinesisStreamSink} after disabling {{AIMDRatelimitingStrategy}}
> h2. Environment Settings
> - Benchmarking was performed on AWS KDA.
> - Application logic is just sending records downstream
> - Application parallelism was tested to be 1.
> - Kinesis stream number of shards was tested with 8 and 12.
> - payload size was 1Kb and 100Kb.
