-----------------------------------------
Summary: EMA for buffer debloat level
Key: FLINK-24470
URL: https://issues.apache.org/jira/browse/FLINK-24470
Project: Flink
Issue Type: Improvement
Components: Runtime / Checkpointing
Affects Versions: 1.14.0
Reporter: Anton Kalashnikov
Assignee: Anton Kalashnikov
Right now, we use EMA for the smoothing calculation of the throughput. But
there is an idea to use EMA on the buffer debloat(BufferDebloater) level
because it contains more information(old buffer size, current throughput,
buffer in use count, etc.) and it looks like it should be used more effectively.
!NB. This is just an idea which makes sense to try. but if the new
implementation doesn't have real profit it makes sense to keep the old one.
