[jira] [Updated] (OAK-4464) Move FileStore.ChangeDispatcher to
TarRevisions
[ https://issues.apache.org/jira/browse/OAK-4464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Dürig updated OAK-4464:
-------------------------------
Description:
{{ChangeDispatcher}} should move from {{SegmentNodeStore}} to {{TarRevisions}}. With this change we should be able to remove the additional tracking of the head state in {{SegmentNodeStore}} and fully rely on the {{TarRevisions}} instance. The {{commitSemaphore}} and {{refreshHead}} method would disappear from {{SegmentNodeStore}} as they would be now implementation details of {{TarRevisions}}.
AFAIK, this is the last missing piece to be able to replace the commit semaphore with a real scheduler (OAK-4122).
