-----------------------------------
Summary: Ability to remove old metadata for structure streaming
MetadataLog
Key: SPARK-15698
URL: https://issues.apache.org/jira/browse/SPARK-15698
Project: Spark
Issue Type: Improvement
Components: SQL, Streaming
Reporter: Saisai Shao
Priority: Minor
Current MetadataLog lacks the ability to remove old checkpoint file, we'd
better add this functionality to the MetadataLog and honor it in the place
where MetadataLog is used, that will reduce unnecessary small files in the long
running scenarios.
