cassandra-cli list <CF> limit number of columns returned
--------------------------------------------------------

                 Key: CASSANDRA-3012
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3012
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 0.8.3
            Reporter: Aaron Turner
            Priority: Minor


Right now in the CLI, running: list MyColumnFamily; will return the first 100 rows and quite
easily the bazillion columns associated with those rows.  Often times you're interested in
just the row keys in the CF and less interested in all the columns or perhaps only a subset
of columns.

Hence it would be nice to have the limit option take a second, optional parameter limiting
the number of columns to return:

list MyCF[startkey:] limit 10, 30;

would limit the columns per row to 30 while limiting the number of rows to 10 and starting
at key "startkey".  It should also take values 0 (no columns) and -1 (all columns).  -1 should
also be acceptable as a row limit also denoting "all rows" rather then requiring the user
to type a large positive number.
