Subject [jira] [Commented] (CASSANDRA-9304) COPY TO improvements
Date Mon, 16 Nov 2015 09:34:11 GMT


Stefania commented on CASSANDRA-9304:

There's one test failing in 2.1:

It passes on the 2.2 and 3.0 branches and locally on the 2.1 branch with the 3.0rc driver
installed. It seems the set returned by SELECT is not sorted on Jenkins. I've noticed a similar
problem on the unpatched branch:

Except here it is even worse because we have not added {{SortedSet}} to (which
I have done for this patch).

> COPY FROM has gotten a lot of love.  COPY TO not so much.  One obvious improvement could
be to parallelize reading and writing (write one page of data while fetching the next).
