Subject [jira] [Created] (AMQ-4662) KahaDB default checksumJournalFiles to true
Date Thu, 01 Aug 2013 10:53:48 GMT
Gary Tully created AMQ-4662:
-------------------------------

             Summary: KahaDB default checksumJournalFiles to true
                 Key: AMQ-4662
                 URL: https://issues.apache.org/jira/browse/AMQ-4662
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Message Store
    Affects Versions: 5.8.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.9.0


A checksum allows us to validate and ignore missing/corrupt journal files (both of which are
optional). It is too late to enable checksumJournalFiles after the fact of corruption. Best
to have it on by default and take the small performance penalty so that in the rare event
of corruption we have some options. Folks who don't care about the integrity of the journal
can disable it.
