Aleksey Yeschenko updated CASSANDRA-7394:
-----------------------------------------
Priority: Trivial (was: Minor)
> Optimize CollationController#collectTimeOrderedData() to potentially skip the
> sstables altogether
> -------------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-7394
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7394
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Trivial
>
> As of now, collectTimeOrderedData() will try to read from at least one
> sstable, even if the memtable has a row tombstone with a higher timestamp
> than any max timestamp in the sstable. If we initiate mostRecentRowTombstone
> with the value from the memtables and not Long.MIN_VALUE, reading from the
> sstables can be avoided entirely in this scenario.
