Description:
h1. Issue
As part of FLINK-31772
I performed a complete benchmark for
was:
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.
