1 Memorystore for Redis blocks the CONFIG command, which stops you
from modifying the redis.conf file for your Redis server. However, you can
use the gcloud CLI to modify a defined set of Supported Redis configurations.
Replication backlog for Standard Tier instances
Standard Tier Memorystore for Redis instances reserve 10% of primary-node memory for replication backlog usage. When monitoring your instance, this backlog appears in the used memory metric, even if the instance is empty.
You can only run one admin operation at a time
Examples of Memorystore for Redis admin operations are resizing, renaming, and changing other Redis instance configurations. Only one of these commands can be run at a time. You will have to wait for any admin operation to complete before you can run another one. During these operations, you can still run Redis commands and access the data in the Redis instance.
Quotas and limits
