When HeatWave is enabled and the data you want to query is loaded, queries that qualify are automatically offloaded from the MySQL DB System to HeatWave for accelerated processing. No special action is required. Simply run the query from a client, application, or interface that is connected to the MySQL DB System associated with the HeatWave Cluster. After HeatWave processes a query, results are sent back to the MySQL DB System and to the client, application, or interface that issued the query.

As of MySQL 8.4.0, HeatWave supports InnoDB partitions. Query processing in HeatWave can access partitions with standard syntax.

For information about connecting to a MySQL DB System on HeatWave Service:
