["Sijie Guo (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/BOOKKEEPER-82?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sijie Guo updated BOOKKEEPER-82:
--------------------------------

    Attachment: bookkeeper-82.patch

attach a patch to support rolling journals

1) LogMark should use marked lastMark to safely ensure the entries before lastMark are all persisted.

2) relaying journal can start from last marked log, which can speed up bookie startup

3) bookie.getHandle needs to check whether the ledger existed in current node, not just checking the memory.

> now bookkeeper is writing a single journal file, so the journal file has no chance to be garbage collected and the disk space keeps growing.
