Row-store with no compression is used by default when you create a table in AnalyticDB for PostgreSQL. To enable column-store and compression, you must specify the column-store and compression options when creating the table. For example, you can add the following statement to the tabulation statements to enable the two features.
with (APPENDONLY=true, ORIENTATION=column, COMPRESSTYPE=zlib, COMPRESSLEVEL=5, BLOCKSIZE=1048576, OIDS=false)
In general, we recommend that you enable column-store and compression, especially when you have a lot of complicated queries to the table, or when you want to reduce the storage cost. See Define storage models for tables.
