Subject [jira] [Commented] (HBASE-8228) Investigate time taken to snapshot memstore
Date Wed, 26 Jun 2013 22:34:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8228?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13694319#comment-13694319

Amitanand Aiyer commented on HBASE-8228:
----------------------------------------

I think open source is using one memstore flusher.

Multiple memstore flush threads was added pretty recently. This was part of the efforts to
reduce the time it takes to send machines to repairs etc.

> Snapshotting memstores is normally quick. But, sometimes it seems to take long. This
JIRA is to track the investigation and fix to improve the outliers.
