Console

1. In the Google Cloud console, go to theMemorystore for Valkey page.

   Memorystore for Valkey

2. Click your instance ID.

3. In theConfigurations section, click the pencil icon next toShards.

4. In theShards field, enter the number of shards to which you want toscale your instance.

5. ClickUpdate instance.

gcloud

To scale the number of shards for an instance, use thegcloud memorystore instances update command:

gcloud memorystore instances updateINSTANCE_ID \--location=REGION_ID \--shard-count=SHARD_COUNT

Replace the following:

• INSTANCE_ID: the ID of your instance.
• REGION_ID: the region where your instance is located.
• SHARD_COUNT: the number of shards in your instance. The shardcount determines the total memory capacity for storing instance data. For moreinformation about instance and node specifications for Memorystore for Valkey instances, seeInstance and node specification.

For example:

gcloud memorystore instances update my-instance \--location=us-central1 \--shard-count=8

gcloud

1. To retrieve information about an instance, use thegcloud memorystore instances describe command:

   gcloud memorystore instances describeINSTANCE_ID \--location=REGION_ID

   Replace the following:

   • INSTANCE_ID: the ID of your instance
   • REGION_ID: the region where your instance is located (for example,us-central1)

2. Check the output to see if the following conditions exist:

   1. The output contains anengineConfigs section.

   2. Themaxmemory-clients,maxmemory, ormaxclients parameters appearin this section.

   If any of these parameters appear, then when you scale the node type for theinstance, you must scale the values for the parameters to reflect valuesthat Memorystore for Valkey can accept for the scaled node type. For moreinformation, seeModifiable configuration parameters.

3. To scale the node type, use thegcloud memorystore instances update command:

   gcloud memorystore instances updateINSTANCE_ID \--location=REGION_ID \--node-type=NODE_TYPE

   Replace the following:

   • INSTANCE_ID: the ID of your instance.
   • REGION_ID: the region where your instance is located.

   • NODE_TYPE: the node type to which you want to scale yourinstance. Acceptable values for this parameter areshared-core-nano,standard-small,highmem-medium, andhighmem-xlarge.

     Note: You can't scale your instance down to theshared-core-nano node type.Caution: We recommend that you use theshared-core-nano node type for development or testing purposesonly because this node type has no SLA. If you run Memorystore for Valkey in aproduction environment, then we recommend using thestandard-small,highmem-medium, orhighmem-xlarge node types. For moreinformation about these node types, seeChoose a node type.

   For this example, you scale the node type of themy-instance instance tohighmem-medium. This instance is located in theus-central1region.

   gcloud memorystore instances update my-instance \--location=us-central1 \--node-type=highmem-medium

   For this example, you change the value of themaxclients parameter to15,000.

   gcloud memorystore instances update my-instance \--location=us-central1 \--node-type=highmem-medium \--update-engine-configs=maxclients=15000
