This page describes how to scale Memorystore for Redis instances. For more information about an instance's behavior during scaling, see Instance scaling behavior.
Best practices for scaling an instance
We recommend exporting your instance data before scaling your operation.
For Standard Tier instances, to increase the speed and reliability of your scaling operation, scale your instance during periods of low instance traffic. To learn how to monitor instance traffic, see Monitoring Redis instances.
When reducing a Standard Tier instance's capacity, you must choose a size greater than the amount of data being stored or scaling fails.
- For example, if you have a 10 GB instance that has 5.5 GB of data stored in it, you can resize the instance to a minimum of 6 GB. The amount of storage your instance uses is visible on its details page in the Google Cloud console.
Instance scaling instructions
Console
- Go to the Memorystore for Redis page in the Google Cloud console.
Memorystore for Redis - Click the Instance ID of the instance you want to resize.
- Click Edit.
- Under Capacity, enter a new size in the field to update the instance's capacity.
- Click Save.
Gcloud
Enter the following command, replacing variables with appropriate values:
gcloud redis instances update instance-id --region=region-id --size=size
Where:
- instance-id is your instance ID.
- region-id is the region ID.
- size is the desired instance size in gibibytes (GiB).
For example:
gcloud redis instances update myinstance --region=us-central1 --size=100
