Avi Kivity c1aed26377 Merge "More fixes for ORDER BY clauses"
"These patches fix more problems related to ORDER BY clauses.
Firstly, mutation_partition::query() can now return rows in reveresed
order which makes it easy for select statements to ask for data from
single partition with clustering keys in reversed order even if limit
of rows is set.
That alone is not sufficient, though, if the request contains IN clause
on partition keys and number of returned rows is limited. The information
needed to determine which rows need to be in the reply isn't available
before post-query sort is done, so select statement asks for more rows
than the limit and trims the output later."
