Subject [jira] [Commented] (CASSANDRA-7622) Implement virtual tables
Date Wed, 04 Apr 2018 17:35:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16425902#comment-16425902

Jeremiah Jordan commented on CASSANDRA-7622:
--------------------------------------------

Since we specify replication at the keyspace level, I also think it would be very confusing
to have non-replicated virtual tables mixed in to some other keyspace.  Those replication
settings are used by drivers and other tools to figure out how to handle the tables that use
them, it makes the most sense to me for virtual tables to follow the same logic, rather than
becoming even more special.

> 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.
