Subject [jira] [Commented] (HBASE-14895) Seek only to the newly flushed file on scanner reset on flush
Date Fri, 04 Dec 2015 12:46:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15041527#comment-15041527

Anoop Sam John commented on HBASE-14895:
----------------------------------------

After HBASE-13082, we will notify ChangedReadersObserver only after a flush operation. After
bulk load and compaction we dont need inform the readers. After a flush, which results in
exactly one file, the notify mechanism can pass that file's detail also? So on that we can
do the reset.  We will remove the scanner on the snapshot also (?)..  So this can be achieved
with lesser code change?  Rather than maintain new Lists and all?
