This is the first of 3 tickets, the other two are CASSANDRA-9302 and CASSANDRA-9303, where we will continue the refactoring initiated in this ticket for COPY TO and extend it to COPY FROM and the COPY options. As a final step the new classes will be moved to a new file (once COPY FROM is also enhanced). It would help if the person reviewing this ticket could also review the other two tickets once they are available. 2.1 CI: http://cassci.datastax.com/view/Dev/view/stef1927/job/stef1927-9304-2.1-dtest/ > COPY TO improvements > -------------------- > > Key: CASSANDRA-9304 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9304 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Jonathan Ellis > Assignee: Stefania > Priority: Minor > Labels: cqlsh > Fix For: 2.1.x > > > 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
