Sylvain Lebresne commented on CASSANDRA-13787:
----------------------------------------------
Sorry for the delay reviewing, but patch lgtm (though, to make extract sure
we're on the same page, this appear to only include the fix for the "first
problem" since the "second problem" seems to have been included in
CASSANDRA-11500).
Have you run CI on this? Also, if you could provide branches for all branches,
that would be amazing (the fix itself should merge up cleanly, but I suspect
the tests may require a few minor updates).
> RangeTombstoneMarker and ParitionDeletion is not properly included in MV

> Key: CASSANDRA-13787
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13787
> Project: Cassandra
> Issue Type: Bug
> Components: Local Write-Read Paths, Materialized Views
> Reporter: ZhaoYang
> Assignee: ZhaoYang
>
> Found two problems related to MV tombstone.
> 1. Range-tombstone-Marker being ignored after shadowing first row, subsequent
> base rows are not shadowed in TableViews.
> If the range tombstone was not flushed, it was used as deleted row to
> shadow new updates. It works correctly.
> After range tombstone was flushed, it was used as RangeTombstoneMarker
> and being skipped after shadowing first update. The bound of
> RangeTombstoneMarker seems wrong, it contained full clustering, but it should
> contain range or it should be multiple RangeTombstoneMarkers for multiple
> slices(aka. new updates)
> -2. Partition tombstone is not used when no existing live data, it will
> resurrect deleted cells. It was found in 11500 and included in that patch.-
> (Merged in CASSANDRA-11500)
> In order not to make 11500 patch more complicated, I will try fix
> range/partition tombstone issue here.
