-If enabled, file compaction will merge multiple small files into larger files
based on the target file size.
-When running file compaction in production, please be aware that:
-- Only files in a single checkpoint are compacted, that is, at least the same
number of files as the number of checkpoints is generated.
-- The file before merging is invisible, so the visibility of the file may be:
checkpoint interval + compaction time.
-- If the compaction takes too long, it will backpressure the job and extend
the time period of checkpoint.
+启用该参数后，文件压缩功能会根据设定的目标文件大小，合并多个小文件到大文件。
Review comment:
好的，我再检查下，统一修改为“合并”。
