[jira] [Commented] (AURORA-1959) Missing Ops prevent upgrade from 0.19 to master

    [ https://issues.apache.org/jira/browse/AURORA-1959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16284103#comment-16284103 ] 

Bill Farner commented on AURORA-1959:
-------------------------------------

Just as a shared mental note - if/when we have a snapshot-less storage, we will need an explicit delete to expunge deprecated record types.

> Ops removed between 0.19 and master causes issues when replaying logs. Because the Op no longer exists in the new version, the scheduler will throw an exception and fail during recovery.
> The fix here is to deprecate operations over different versions. Do not write for one version and reads are no-ops. Then, you can remove the Op.
