2.16.1 Secondary Engine Definitions

To identify tables on the MySQL DB System that are defined with a secondary engine, query the CREATE_OPTIONS column of the INFORMATION_SCHEMA.TABLES table. The CREATE_OPTIONS column shows the SECONDARY_ENGINE clause, if defined. Tables with SECONDARY_ENGINE="RAPID" are loaded into HeatWave, and changes to them are automatically propagated to their counterpart tables in the HeatWave Cluster.

mysql> SELECT TABLE_SCHEMA, TABLE_NAME, CREATE_OPTIONS 
          FROM INFORMATION_SCHEMA.TABLES
          WHERE CREATE_OPTIONS LIKE '%SECONDARY_ENGINE%' AND TABLE_SCHEMA LIKE 'tpch';
+--------------+------------+--------------------------+
| TABLE_SCHEMA | TABLE_NAME | CREATE_OPTIONS           |
+--------------+------------+--------------------------+
| tpch         | customer   | SECONDARY_ENGINE="RAPID" |
| tpch         | lineitem   | SECONDARY_ENGINE="RAPID" |
| tpch         | nation     | SECONDARY_ENGINE="RAPID" |
| tpch         | orders     | SECONDARY_ENGINE="RAPID" |
| tpch         | part       | SECONDARY_ENGINE="RAPID" |
| tpch         | partsupp   | SECONDARY_ENGINE="RAPID" |
| tpch         | region     | SECONDARY_ENGINE="RAPID" |
| tpch         | supplier   | SECONDARY_ENGINE="RAPID" |
+--------------+------------+--------------------------+

You can also view create options for an individual table using SHOW CREATE TABLE.
