map_name
Name of an existing contiguous or sparse map.
You cannot specify TD_DataDictonaryMap or TD_GlobalMap.
COLOCATE USING colocation_name
Name for colocating the table on the same AMPs with other tables, join indexes, or hash indexes. For example, you can colocate two tables, then join the tables on the primary index or primary AMP index columns.
You cannot specify this option if you are altering the table to use a contiguous map. For a contiguous map, a colocation name is not needed for colocation and colocation_name is set to NULL.
If you do not want to colocate the table, do not specify this option.
