Aleksey Yeschenko commented on CASSANDRA-7622:
----------------------------------------------
The right level of abstraction, for both this and pluggable storage, is on
keyspace level. The basic write unit we have is a {{Mutation}}, and you have to
accept this. What would not be acceptable is if-else conditions in
{{Keyspace.apply()}} depending on what the kind of table this is.
Additionally, all tables in a keyspace by definition share the same replication
strategy and params, and I just don't see how you can mix and match regular and
virtual ones in the same keyspace.

> Key: CASSANDRA-7622
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7622
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Tupshin Harper
> Assignee: Chris Lohfink
> Priority: Major
> Fix For: 4.x
>
>
> There are a variety of reasons to want virtual tables, which would be any
> table that would be backed by an API, rather than data explicitly managed and
> stored as sstables.
> One possible use case would be to expose JMX data through CQL as a
> resurrection of CASSANDRA-3527.
> Another is a more general framework to implement the ability to expose yaml
> configuration information. So it would be an alternate approach to
> CASSANDRA-7370.
> A possible implementation would be in terms of CASSANDRA-7443, but I am not
> presupposing.
