Memorystore for Redis supports a subset of the native Redis configuration
parameters that you can modify to customize the
behavior of your Redis instance. Other Redis configuration parameters are set
to default values and cannot be modified.
Configuration changes take place immediately, don't require a restart of the
instance, and are saved if the instance restarts. You can update modifiable
configuration parameters after instance creation.
For tables showing acceptable values for modifiable parameters
and default values for unmodifiable parameters, see the Redis configurations
reference page.
Viewing and updating configurations in the Google Cloud console
Go to the Memorystore for Redis page in the Google Cloud console.

right of a configuration to delete it, or click Add Configuration to add
a new configuration.
Setting and updating configuration parameters with the Google Cloud CLI
You can set modifiable configuration parameters when creating or updating an
instance. To set a configuration parameter during creation, enter the following
command, replacing the highlighted-variables with the appropriate
values:
