[jira] [Commented] (FLINK-27708) Add background compaction task for append-only table when ingesting.

    [ https://issues.apache.org/jira/browse/FLINK-27708?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17555851#comment-17555851 ]

----------------------------------------

I want to try to do this work. There are some studies on leveldb compact before. The current issue means that the compact function supported in MergeTreeWriter is supported in AppendOnlyWriter.

> We could still execute compaction task to merge small files in the background for append-only table, although it won't reduce any delete markers when comparing to the merge tree table.
