Subject [jira] [Commented] (CASSANDRA-9304) COPY TO improvements
Date Wed, 04 Nov 2015 00:06:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14988524#comment-14988524

Stefania commented on CASSANDRA-9304:
-------------------------------------

Unfortunately testing on Windows revealed there is a bit more work to do. It appears multiprocessing
on Windows is more limited: because of the lack of {{os.fork}}, the worker process class has
to be _picklable_. This means changing a few things.

> 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).
