Subject [jira] [Created] (CASSANDRA-2777) Pig storage handler should implement LoadMetadata
Date Wed, 15 Jun 2011 22:44:50 GMT
Pig storage handler should implement LoadMetadata
-------------------------------------------------

                 Key: CASSANDRA-2777
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2777
             Project: Cassandra
          Issue Type: Improvement
          Components: Contrib
            Reporter: Brandon Williams
            Assignee: Brandon Williams
            Priority: Minor


The reason for this is many builtin functions like SUM won't work on longs (you can workaround
using LongSum, but that's lame) because the query planner doesn't know about the types beforehand,
even though we are casting to native longs.

There is some impact to this, though.  With LoadMetadata implemented, existing scripts that
specify schema will need to remove it (since LM is doing it for them) and they will need to
conform to LM's terminology (key, columns, name, value) within the script.  This is trivial
to change, however, and the increased functionality is worth the switch.
