Subject [GitHub] flink issue #3801: [FLINK-6364] [checkpoints] Implement incremental checkpoi...
Date Tue, 02 May 2017 09:58:11 GMT
Github user StefanRRichter commented on the issue:

    @gyfora this is already happening in the code: the backend tracks which files are already
transferred to hdfs, and a reference counting in the checkpoint coordinator (introduced in
FLINK-6014) takes care of deleting SSTable files from the shared HDFS directory that are no
longer referenced by any incremental checkpoint.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
