Hudson commented on HBASE-10094: -------------------------------- SUCCESS: Integrated in hbase-0.96-hadoop2 #144 (See [https://builds.apache.org/job/hbase-0.96-hadoop2/144/]) HBASE-10094 Add batching to HLogPerformanceEvaluation (stack: rev 1548913) * /hbase/branches/0.96/hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/wal/HLogPerformanceEvaluation.java > Add batching to HLogPerformanceEvaluation > ----------------------------------------- > > Key: HBASE-10094 > URL: https://issues.apache.org/jira/browse/HBASE-10094 > Project: HBase > Issue Type: Sub-task > Components: Performance, wal > Reporter: stack > Assignee: Himanshu Vashishtha > Fix For: 0.98.0, 0.96.1, 0.99.0 > > Attachments: 10094v2.txt, addendum.0.96.txt > > > As Himanshu points out in the the parent issue, HLogPE is using an unorthodox > API appending edits to the WAL; it is using an API that is meant for tests > only that does an append immediately followed by a sync call. > In normal deploy, WAL appends are done as a bunch of appends followed by a > sync on the tail of the transaction -- not a sync per append. > This issue is about changing HLogPE to use append and then sync. It also > adds an argument so you can specifying batching of a set of appends before > the sync is called. The latter lets HLogPE mimic multi puts that use the > minibatch... which appends, appends, appends.. and then syncs. > Assigning to Himanshu for review. -- This message was sent by Atlassian JIRA (v6.1#6144)
