We need to set things up such that we have a 10 minute pre commit build, and a longer running test of tests (unbounded for all intents/purposes). Mainly this requires us to categorize our tests. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
Hello, I have a question about the performance improvement from 3.1 to 3.2
Dear sir: It is said In version 3.2 r/w performance improved by ~2x compared to the previous 3.1 releasehttp://hadoop.apache.org/zookeeper/docs/r3.1.1/zookeeperOver.html#Performance. I have diff the src of the tow version, and find out the difference of FileTxnLog.java, which uses BufferedOutputStream. Could you tell me some detail about the performance improvement. Like algorithm, coding, data structure optimization. Thank you for your help. Lionel.Dai
