Quotas and limits

Note: If you are looking for the Memorystore for Redis Cluster documentation, see Quotas and limits.

This document contains the current resource capacity limits and per-second API request quotas for Memorystore for Redis.

Instance limits

Memorystore for Redis enforces the following usage limits:

Limit	Value^1
Databases per instance	16
Connected clients per instance for Basic Tier	65,000
Connected clients per instance for Standard Tier	65,000
Connected clients per instance for Standard Tier with read replicas	65,000 for each node including the primary and read replicas

¹ For instances that use both in-transit encryption and Redis version 6.x or earlier, connection limits can be lower. For more information, see Connection limits for in-transit encryption.

Regional capacity quota

The default per-project quota for Memorystore for Redis allows you to provision 1 TB of Redis capacity in each region where the service is available.

Quota	Value
Data provisioned per region	1 TB

For example, if you provision three instances in your project with 300 GB each in us-central1, you will have consumed 900 GB out of the 1  TB quota for us-central1. With the default quota, you can provision an additional 100 GB in us-central1. To request a higher quota for a region, see Regional capacity quota increases.

Regional capacity quota increases

To request a higher regional capacity for your project, follow these steps:

1. Go to the Quotas page in the Google Cloud console.
   Quotas
2. From the Services drop down, select Memorystore for Redis API.
3. From the list of quotas, click the checkbox next to the quota labeled Total Redis capacity (GB) for the desired region.
4. Click the Edit Quotas button.
5. In the edit pane, enter your contact information, then click Next.
6. Enter your desired quota, then click Done.
7. Click Submit request.

Per-second API requests quota

Note:

• You cannot request a quota increase for Memorystore for Redis API operations, such as instance create, update, and export. There is no limit to the number of Redis commands you can run, such as Redis SET, GET, and DEL.
• Follow the Exponential backoff recommendations to reduce the number of API requests made if an error is encountered.

The per-second quota for Memorystore for Redis API requests/operations is as follows, and is subject to change:

API Requests Quota	Value
API Requests per 100 seconds	5,000

Memorystore for Redis API operations include:

• Get operations (gcloud redis instances describe)

• List operations (gcloud redis instances list)

• Create operations

• Import/export operations

• Update operations

This quota is for redis.googleapis.com requests/operations, not OSS Redis protocol/commands. These limits apply to each Google Cloud console project and are shared across all applications and IP addresses using that project.
