-----------------------------------
Summary: CLONE - AsyncSinkWriter Performance regression due to AIMD rate limiting strategy
Key: FLINK-31872
URL: https://issues.apache.org/jira/browse/FLINK-31872
Project: Flink
Issue Type: Bug
Components: Connectors / Common, Connectors / Firehose, Connectors / Kinesis
Affects Versions: 1.16.0, aws-connector-3.0.0, 1.16.1, aws-connector-4.0.0, aws-connector-4.1.0
Reporter: Ahmed Hamdy
Assignee: Ahmed Hamdy
Fix For: 1.16.2, 1.18.0, 1.17.1, aws-connector-4.2.0
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.
