Aleksey Yeschenko commented on CASSANDRA-9596:
----------------------------------------------

We do for {{collectTimeOrderedData()}} since CASSANDRA-7394 (2.0.9). I did miss 
{{collectAllData()}} there, though.

Benedict fixed it in CASSANDRA-9228 (2.1.6).

> If you have one SSTable containing a partition level tombstone at timestamp t 
> and all other SSTables have cells with timestamp < t, Cassandra will skip all 
> the other SSTables and return nothing quickly. However, if the partition 
> tombstone is still in the memtable it doesn’t skip any SSTables. It should 
> use the same timestamp logic to skip all SSTables.
