Brian Hess commented on CASSANDRA-8234:
----------------------------------------
Another question:
6. If we include Spark in Cassandra, what are we going to do about the Spark
Master? That is, a feature of Cassandra (CTAS) will depend on a system that
does not have the same HA profile (namely, always-on) as Cassandra. Will we
modify Spark to be "masterless"? Will this ticket have a dependency on a
"masterless" OSS Spark? Or will Cassandra have this as a SPOF?

> Key: CASSANDRA-8234
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8234
> Project: Cassandra
> Issue Type: New Feature
> Components: Tools
> Reporter: Robin Schumacher
> Fix For: 3.x

>
> Continuous request from users is the ability to do CREATE TABLE AS SELECT.
> The simplest form would be copying the entire table. More advanced would
> allow specifying thes column and UDF to call as well as filtering rows out in
> WHERE.
> More advanced still would be to get all the way to allowing JOIN, for which
> we probably want to integrate Spark.
