-------------------------------------
Labels: LWT (was: )
> Regression in 3.0, breaking the fix from CASSANDRA-6069
> -------------------------------------------------------
>
> Key: CASSANDRA-13793
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13793
> Project: Cassandra
> Issue Type: Bug
> Reporter: Sylvain Lebresne
> Assignee: Sylvain Lebresne
> Priority: Major
> Labels: LWT
> Fix For: 3.0.x, 3.11.x
>
>
> The goal of the fix of CASSANDRA-6069 was to make sure that collection
> tombstones in an update in CAS were using {{t-1}} because at least in
> {{INSERT}} collection tombstones are used to delete data prior to the update
> but shouldn't delete the newly inserted data itself. Because in 2.x the
> collection tombstones are normal range tombstones and thus part of the
> {{DeletionInfo}}, we went with the easy solution of using {{t-1}} for all of
> {{DeletionInfo}}.
> When moving that code to 3.0, this was migrated too literally however and
> only the {{DeletionInfo}} got the {{t -1}}. But in 3.0, range tombstones are
> not part of {{DeletionInfo}} anymore, and so this is broken.
> Thanks to [~aweisberg] for noticing this.
