[jira] [Created] (AMQ-8254) KahaDB index does not shrink on cleaning in-use data files

Vasa created AMQ-8254:
-------------------------

             Summary: KahaDB index does not shrink on cleaning in-use data files
                 Key: AMQ-8254
                 URL: https://issues.apache.org/jira/browse/AMQ-8254
             Project: ActiveMQ
          Issue Type: Bug
          Components: KahaDB
    Affects Versions: 5.15.4
            Reporter: Vasa


KahaDB index keeps growing over time which occupies broker disk space.

The index does not shrink when in-use journal files are cleared after messages from the broker are consumed.

Further, on unclean shutdown of the broker the known free pages are lost and no longer tracked. This causes new pages to be created which takes up further more disk space.
