Targeted business outcomes - AWS Prescriptive Guidance

Targeted business outcomes

You can use this guide to achieve the following business outcomes with cluster cache management (CCM):

  • In the event of a failover, recover quickly to help maintain stable and optimal workload performance.

  • Reduce business losses caused by poor workload performance after a failover.

  • Help prevent unnecessary I/O costs after a failover.

You can use this guide to achieve the following business outcomes with query plan management (QPM):

  • Improve plan stability by forcing the optimizer to choose from a small number of approved plans. This prevents the optimizer from selecting a sub-optimal plan for a given SQL statement after system or database changes.

  • Optimize plans centrally and then distribute them globally.

  • Determine which indexes aren't being used, and evaluate the effects of adding or removing an index.

  • Automatically recognize any new minimum-cost plans that the optimizer identifies.

  • Test new optimizer features with minimal risk because you can decide to accept only the plan changes that improve performance.
