             Summary: Range-partition naming
                 Key: KUDU-1687
                 URL: https://issues.apache.org/jira/browse/KUDU-1687
             Project: Kudu
          Issue Type: Bug
    Affects Versions: 1.0.0
            Reporter: Dan Burkert


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.
