     [ https://issues.apache.org/jira/browse/BOOKKEEPER-717?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sijie Guo updated BOOKKEEPER-717:
---------------------------------

    Attachment: BOOKKEEPER-717.diff

attach a patch to forward group timeout entries, which would reduce number for force writes. since it is a performance change, there is no separated test case for it.

> journal should look a bit forward to group timeout entries, which avoid too much fsyncs with single entry impacting journal performance. so bookie could have sustained high throughput with low-latency.
