Jeremiah Jordan commented on CASSANDRA-5640:
--------------------------------------------
Just came up with one reason to need this. Getting counter and non counter
data in the same query.
> Allow JOIN on partition key for tables in the same keyspace
> -----------------------------------------------------------

> Key: CASSANDRA-5640
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5640
> Project: Cassandra
> Issue Type: New Feature
> Components: API
> Reporter: Jeremiah Jordan
> Priority: Minor
> Labels: cql
>
> People whine about there not being any JOIN in CQL a lot. I was thinking we
> could add JOIN with the restriction that you can only join on partition key,
> and only if the tables are in the same keyspace. That way it could be done
> local to each node, and would not need to be a true distributed join.
> Feel free to shoot me down ;)
