Subject [jira] [Commented] (HBASE-5699) Should we use muti HLog or Writer in HLog in a HRegionServer
Date Wed, 04 Apr 2012 09:58:23 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246144#comment-13246144

binlijin commented on HBASE-5699:
---------------------------------

@stack, 
There is only one HLog and a Writer in a HRegionServer for write-ahead-log, at any time only
one writer takes the HLog lock and the other will wait. If there are muti HLog or Writer,
the write-ahead-log can be run parallel, the write performance should be improved.
