>                 Key: CASSANDRA-7394
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7394
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Aleksey Yeschenko
>            Assignee: Aleksey Yeschenko
>            Priority: Minor
>
> As of now, collectTimeOrderedData() will try to read from at least one sstable, even
if the request can be fulfilled from the memtable exclusively.
> If we initiate mostRecentRowTombstone with the value from the memtables and not Long.MIN_VALUE,
reading from the sstables can be avoided entirely.
