> It would be nice if individual range partitions could be named during creation, so that they can be dropped by name later.  For example, it would allow a SQL layer to do the following:
> {code}
> CREATE TABLE t (
>     c INT32 PRIMARY KEY,
> )
> PARTITION BY
>     RANGE (c) (
>         PARTITION first 100 <= VALUES < 200,
>         PARTITION second 300 <= VALUES < 400,
>     );
> ALTER TABLE t DROP RANGE PARTITION first;
> -- would be equivalent to:
> ALTER TABLE t DROP RANGE PARTITION 100 <= VALUES < 200;
> {code}
> Right now there is no state associated with range partitions in the master, so this may have to be approximated by adding per-tablet metadata, and then adding an associated range partition name to that.
