Hyukjin Kwon resolved SPARK-30804. ---------------------------------- Fix Version/s: 3.0.0 Resolution: Fixed Issue resolved by pull request 27557 [https://github.com/apache/spark/pull/27557] > Measure and log elapsed time for "compact" operation in > CompactibleFileStreamLog > -------------------------------------------------------------------------------- > > Key: SPARK-30804 > URL: https://issues.apache.org/jira/browse/SPARK-30804 > Project: Spark > Issue Type: Improvement > Components: Structured Streaming > Affects Versions: 3.1.0 > Reporter: Jungtaek Lim > Assignee: Jungtaek Lim > Priority: Major > Fix For: 3.0.0 > > > "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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
