Subject [jira] Commented: (HBASE-1416) Pool of commit loggers in each HRegionServer
Date Sat, 19 Dec 2009 22:52:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12792924#action_12792924

stack commented on HBASE-1416:
------------------------------

Below are Ryan's comments from the list.

"With deferred log flush we can choose between high durability and speed on a
per table basis. I think we should shelf this for now, since with write
buffering in the client and the adjusted sync calls, we are very fast at
bulk data import."

J-D says write speeds are up with hbase-1939.

I'm good w/ punting out to 0.22 or beyond.  Let me move it.

> HBASE-1394 discusses pools of loggers as means of our being able to dump out the logs
faster; commit log is log pole in a write transaction.   This issue is about implementing
the pool of writers.
