Brian Hess commented on CASSANDRA-9302:
----------------------------------------
There is also https://issues.apache.org/jira/browse/CASSANDRA-9048 That ticket
has been tagged as "Later" for some reason, 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)
> Optimize cqlsh COPY FROM, part 3
> --------------------------------
>
> Key: CASSANDRA-9302
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9302
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Jonathan Ellis
> Assignee: David Kua
> Fix For: 2.1.x
>
>
> 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.
