Instance usage units
The per-project instance usage units for a Memorystore for Valkey instance is calculated by the following formula:
Instance usage units = (shard_count) * (1 + replica_count)
The regional quota for Memorystore for Valkey limits the total amount of usage units that you can provision across all of your instances in a region.
For example, if you provision three instances in your project with 3 shards and
1 replica each in us-central1
, then you consume 18 units out of the total
regional unit quota for us-central1
.
