Rick Shaw commented on CASSANDRA-2926:
--------------------------------------
With 176 methods, what are the odds I guess right on all :) So let me say first
off, I be glad to change any values. But here are my excuses...
- allTablesAreSelectable -- references whether the user can use all the tables
returned by {{getTables()}}, which is not currently supported. We return an
empty {{ResultSet}}. Since we did not return any tables in the result from that
method call I went with {{false}}.
- getMaxBinaryLiteralLength
- getMaxCharLiteralLength
Zero (0) implies no limit or the limit was unknown, and as I did not know of
any such limit except practicality I went with zero. I could not find any
documented limits but if I missed them somewhere I will gladly put them in.
- [own|others][Deletes|Inserts|Updates]AreVisible -- no good excuse for them
being {{false}}. I must have been confused by all the questions running
together. I will make them {{true}} in the subsequent patch.
- supportsUnion -- There is no {{UNION}} statement type in CQL? I answered
{{false}}?

> Key: CASSANDRA-2926
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2926
> 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
>
> Attachments: add-database-metadata-v1.txt

>
> 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.
