> URL: https://issues.apache.org/jira/browse/SPARK-30804
> Project: Spark

>
> "compact" operation in FileStreamSourceLog and FileStreamSinkLog is
> introduced to solve "small files" problem, but introduced non-trivial latency
> which is another headache in long run query.
> There're bunch of reports from community for the same issue (see SPARK-24295,
> SPARK-29995, SPARK-30462) - before trying to solve the problem, it would be
> better to measure the latency (elapsed time) and log to help indicating the
> issue when the additional latency becomes concerns.
