T Jake Luciani commented on CASSANDRA-10261:
--------------------------------------------
bq. I'll switch after that.
Made the name change along with some new changes to the tests (adds real
tombstones)
I also added a new dtest that does the same as the unit test but verifies
digest mismatches [pull

> in CASSANDRA-9664 there are issues dealing with updates to individual cells
> which can mask data from the base table in the view when trying to filter
> data correctly in the view.
> Unfortunately, this same issue exists for all MV tables with regular columns.
> In the earlier versions of MV we did have a fix for this which I now can see
> is ineffective for all situations.
> I've pushed some unit tests to show the issue (similar to tylers) and a fix.
> The idea is we keep the base table's timestamps per cell as it so we can
> *always* tell (per replica) which version of the record is the latest. Since
> the base table *always* writes the entire record to the view (part of our
> earlier partial fix) we can ensure the view record contains *at least* views
> primary key timestamp.
