[jira] [Updated] (SPARK-17879) Don't compact metadata logs
constantly into a single compacted file
[ https://issues.apache.org/jira/browse/SPARK-17879?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Armbrust updated SPARK-17879:
-------------------------------------
Target Version/s: 2.1.0
> Don't compact metadata logs constantly into a single compacted file
> -------------------------------------------------------------------
>
> Key: SPARK-17879
> URL: https://issues.apache.org/jira/browse/SPARK-17879
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 2.0.1
> Reporter: Burak Yavuz
>
> With metadata log compaction, we compact all files into a single file every "n" batches. The problem is, over time, this single file becomes huge, and could become an issue to constantly write out in the driver.
> It would be a good idea to cap the compacted file size, so that we don't end up writing huge files in the driver.
