------------------------------------
Summary: Optimize async compaction in MergeTreeWriter
Key: FLINK-27335
URL: https://issues.apache.org/jira/browse/FLINK-27335
Project: Flink
Issue Type: Improvement
Components: Table Store
Reporter: Jingsong Lee
Assignee: Jingsong Lee
Fix For: table-store-0.2.0
Currently Full Compaction may cause the writer to be blocked, which has an
impact on LogStore latency.
We need to decouple compact and write, compact completely asynchronous.
But too many files will lead to unstable reads, when too many files, Compaction
processing speed can not keep up with Writer, need to back press Writer.
Stop parameter: num-sorted-run.stop-trigger, default 10
