While operating a MySQL HeatWave cluster, you need to resize the HeatWave cluster to accommodate an increased workload. Which method is the most efficient and recommended way to scale the HeatWave cluster?
A.
Manually altering the innodb_buffer_pool_size and restarting the MySQL server.
B.
Using the OCI CLI or Console to adjust the HeatWave cluster's shape and node count.
C.
Modifying the underlying VM shapes of the MySQL Database System.
D.
Recreating the HeatWave cluster with the desired size.
E.
Performing a manual data export and import into a new, larger MySQL Database System.
TheOCI CLI or Consoleprovides a streamlined way to scale the HeatWave cluster. You can easily change theshape and node countthrough the console without significant downtime. The system handles the necessary data redistribution and configuration updates automatically.
This method minimizes disruption and is significantly faster than manual reconfiguration.
OCI’s automated scaling ensures that the cluster maintainsoptimal performancethroughout the operation.
Why the other options are incorrect:
A:Adjusting buffer size affects memory, not cluster size.
C:Changing VM shapes does not directly affect HeatWave.
D:Recreating the cluster is inefficient and time-consuming.
E:Manual export/import introduces downtime and is not efficient for scaling.
