Subject [jira] Commented: (HBASE-1939) HLog group commit
Date Wed, 28 Oct 2009 05:22:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1939?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12770795#action_12770795

Raghu Angadi commented on HBASE-1939:
-------------------------------------

> Wouldn't this leave forceSync to 'true' all the time?
not all the time. forceSync will remain unchanged when 'force' is true. 

syncDone needs to be signaled in finally? Otherwise might leave the waiters hanging.

> Currently multiple clients writing to a RS are serialized when sync'ing their appends.
Implementing group commit can help this by being aware of all the clients in that queue.
