Add autocompression for the column partition. You can add compression to a set of existing columns whether or not the table is empty or contains data. You can only specify autocompression for column-partitioned tables. AUTO COMPRESS applies autocompression to the column or column partition. AUTO COMPRESS is the default. Vantage applies autocompression for a physical row on a per container basis. For efficiency, the system may use the autocompression method chosen for the previous container, including not using autocompression, if that is more effective. You cannot modify the autocompression or partition storage for a column partition more than once in the same ALTER TABLE request.
- NO AUTO COMPRESS
- The column partition containing the column is not autocompressed.
