Subject [jira] [Commented] (CASSANDRA-7666) Range-segmented sstables
Date Fri, 10 Jun 2016 20:04:21 GMT


Jonathan Ellis commented on CASSANDRA-7666:

sstables involved.  We should also (possibly as a separate ticket) be able to leverage this
information in query planning to avoid unnecessary sstable reads.
> Relational databases typically call this "partitioning" the table, but obviously we use
that term already for something else:
