Subject [jira] [Commented] (HBASE-17081) Flush the entire CompactingMemStore content to disk
Date Tue, 17 Jan 2017 10:49:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15825830#comment-15825830

Anastasia Braginsky commented on HBASE-17081:

Because CompositeSnapshot is now "on" by default, all the previous tests are actually now
working with CompositeSnapshot and testing it. However, because the QA was complaining, I
added a test working with previous way of snapshot, meaning flushing only the tail of the
compacting pipeline to the disk. The updated patch is attached (V15).

> Part of CompactingMemStore's memory is held by an active segment, and another part is
divided between immutable segments in the compacting pipeline. Upon flush-to-disk request
we want to flush all of it to disk, in contrast to flushing only tail of the compacting pipeline.
