Subject [jira] [Commented] (HBASE-17914) Create a new reader instead of cloning a new StoreFile when compaction
Date Fri, 14 Apr 2017 09:26:41 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17914?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15968829#comment-15968829

Duo Zhang commented on HBASE-17914:
-----------------------------------

For the readahead thing, I introduced a flag to control it for now. Will open new issues to
remove it. I think we should not use readahead in most cases.
