Subject [jira] [Commented] (HBASE-5954) Allow proper fsync support for HBase
Date Wed, 01 Aug 2012 22:05:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13426949#comment-13426949

Lars Hofhansl commented on HBASE-5954:
--------------------------------------

Created HBASE-6492.
Since I am interested in having this in 0.94 I'll start with the reflection based approach
(but still in trunk for HadoopQA).

This is what I am going to do:
# global HFiles hsync option upon close block (this will also apply sync'ing the WAL on close)
# global WAL edit hsync opion
# hsync CF's HFiles
# hsync CF's WAL edits
# WAL hsync per Put/Delete/Append/Increment/etc
