Starting, Stopping, or Restarting a HeatWave Cluster

A HeatWave Cluster starts automatically after it is created, and the Start button is disabled. A running HeatWave Cluster shows the Active state. For information on HeatWave Cluster states, see HeatWave Cluster Details.

Restarting a HeatWave Cluster with the Restart button shuts down the HeatWave Cluster and then restarts it immediately. Stopping a HeatWave Cluster with the Stop button stops it without restarting.

When a HeatWave Cluster is stopped through a stop or restart action, the data loaded in HeatWave Cluster memory is unloaded. When a HeatWave Cluster restarts, data is reloaded from AWS S3, and includes any changes that occur on the DB System while the HeatWave Cluster is offline.

Start, stop, or restart actions on a HeatWave Cluster have no effect on the DB System with which the HeatWave Cluster is associated.

To start, stop, or restart a HeatWave Cluster:

1. In the MySQL HeatWave Console, select the HeatWave Clusters tab.
2. In the list of HeatWave Clusters, find the HeatWave Cluster you want to start, stop, or restart, and do one of the following:
   • Click on the row of the HeatWave Cluster to highlight it, and then click the Start, Stop, or Restart button.
   • Click the name of the HeatWave Cluster to open the HeatWave Cluster Details page, and then click the Start, Stop, or Restart button.
