Jonathan Ellis commented on CASSANDRA-2926:
-------------------------------------------
bq. We return an empty ResultSet. Since we did not return any tables in the
result from that method call I went with false.
true is also valid then :) Going to go with that so we don't have to remember
to change it, when we do actually ask for tables/CFs.
bq. Zero (0) implies no limit
Added the few limits we have.
bq. no good excuse for them being false
I thought at first this was talking about statement isolation but actually it
is talking about the resultset manipulation api. So false is correct.
bq. There is no UNION operator in CQL?
You're right, but for some reason I keep thinking there is. Sorry. (This
would be the right way to do "multiget." Guess I should create a ticket.)

> Project: Cassandra
> Issue Type: Sub-task
> Components: Drivers
> Affects Versions: 0.8.1, 0.8.4
> Reporter: Rick Shaw
> Assignee: Rick Shaw
> Priority: Minor
> Labels: CQL, JDBC
> Fix For: 0.8.5

> The {{DatabaseMetaData}} interface provides access to meta-data information
> about the JDBC Driver implementation and the DB that it supports. This class
> would usually be used by tooling to discover the extended capabilities of the
> Driver Suite.
> A very basic implementation is planned initially. Non-static metadata about
> Keyspaces and Column Families can be provided in enhanced versions.
