Subject [jira] [Commented] (CASSANDRA-8234) CTAS (CREATE TABLE AS SELECT)
Date Thu, 06 Aug 2015 19:17:06 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14660640#comment-14660640

 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?

> 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.
