This chapter describes how to create and manage HeatWave Clusters.
A HeatWave Cluster consists of a MySQL DB System and one or more HeatWave nodes. The MySQL DB System includes a HeatWave plugin that is responsible for cluster management, query scheduling, and returning query results to the MySQL DB System. HeatWave nodes store data in memory and process queries.
When a HeatWave Cluster is enabled and data is loaded, queries that meet certain prerequisites are automatically offloaded from the MySQL DB System to the HeatWave Cluster for accelerated processing.
