> 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.
