How do I assign a new parameter group to my existing Amazon ElastiCache cluster without restarting the cluster?
Short description
A parameter group acts as a container for engine configuration values. You can apply a parameter group to one or more cache clusters. ElastiCache uses this parameter group to control the runtime properties of your nodes and clusters. You can modify the values in a parameter group for an existing cluster without restarting the cluster.
Resolution
- Create a new parameter group. For detailed steps, see Creating a parameter group.
- Modify the new parameter group and the parameters. For more information, see Modifying a parameter group.
- Modify the cluster to use the new parameter group. For detailed steps, see Modifying an ElastiCache cluster.
