[jira] [Created] (SPARK-17879) Don't compact metadata logs constantly into a single compacted file

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

             Summary: 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: SQL, 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.
