             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.
