Subject [jira] [Comment Edited] (CASSANDRA-9302) Optimize cqlsh COPY FROM, part 3
Date Thu, 06 Aug 2015 04:18:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9302?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14659385#comment-14659385

----------------------------------------------------------------

There is also https://issues.apache.org/jira/browse/CASSANDRA-9048 That ticket has been tagged
as "Later", but the work continues at https://github.com/brianmhess/cassandra-loader
In addition to more options, the performance of cassandra-loader is 4x (or more) than COPY
FROM in 2.1. Also, it is more stable and can handle wider rows (see https://issues.apache.org/jira/browse/CASSANDRA-9552)

> We've had some discussion moving to Spark CSV import for bulk load in 3.x, but people
need a good bulk load tool now.  One option is to add a separate Java bulk load tool (CASSANDRA-9048),
but if we can match that performance from cqlsh I would prefer to leave COPY FROM as the preferred
option to which we point people, rather than adding more tools that need to be supported indefinitely.
> Previous work on COPY FROM optimization was done in CASSANDRA-7405 and CASSANDRA-8225.
