What is Memorystore?
Memorystore is Google’s fully managed in-memory database service. It includes several product variants: Memorystore for Redis (Basic/Standard tier), Memorystore for Redis Cluster, Memorystore for Valkey (compatible with Redis Open Source APIs), and Memorystore for Memcached. Organizations use Memorystore for caching, session storage, and real-time data processing.
The service eliminates the complexity of cluster management, patching, and backups. The cluster variants (Redis Cluster, Valkey) scale without downtime across many nodes and support very high throughput with low latency, including vector search for AI applications. Integration with VPC and Private Service Connect ensures secure connections to Compute Engine and GKE.
Core Features
- Multiple engines: Redis, Valkey, and Memcached as managed services
- Memorystore for Redis Cluster and Memorystore for Valkey for horizontal scaling across many nodes
- Automatic failover and cross-zone replication on high-availability tiers
- Vector search for AI workloads on Redis Cluster and Valkey
- Private Service Connect and VPC integration for secure network configuration
Typical Use Cases
Application Caching: Cache database queries and API responses for faster response times. Reduces database load and improves user experience through low access times.
Session Management: Store user sessions centrally for horizontal scaling of web servers. Every instance accesses the same session data without requiring sticky sessions.
Real-Time Analytics: Counters, leaderboards, and live metrics with Redis/Valkey data structures. Sorted sets enable efficient ranking operations for gaming and social features.
Vector Search: Memorystore for Valkey and Redis Cluster support low-latency vector search for retrieval-augmented generation and recommendation use cases.
Benefits
- Fully managed without your own cluster administration
- Appropriate engine and tier for different scaling requirements
- Protocol compatible with existing Redis, Valkey, and Memcached applications
- Secure network integration via VPC and Private Service Connect

Frequently Asked Questions
What is Memorystore?
Memorystore is Google's fully managed in-memory database service. It includes several product variants - Memorystore for Redis, Memorystore for Redis Cluster, Memorystore for Valkey, and Memorystore for Memcached - for caching, session storage, and real-time processing.
Which engines are supported?
Memorystore supports Redis, the Redis-compatible Valkey, and Memcached. For horizontal scaling across many nodes, Memorystore for Redis Cluster and Memorystore for Valkey are available.
What is the difference between Redis Basic/Standard and Redis Cluster/Valkey?
Memorystore for Redis (Basic/Standard) is suited for smaller, classic Redis workloads. Memorystore for Redis Cluster and Memorystore for Valkey are designed for horizontal scaling across many nodes with very high throughput and low latency, including vector search.
Do I need to modify my application?
No, Memorystore uses standard Redis, Valkey, and Memcached protocols. Existing applications generally work without code changes, usually only connection strings need to be adjusted.
What does Memorystore cost?
Memorystore is billed by instance size, selected tier, and runtime. Higher tiers with high availability and cluster scaling cost more than the Basic tier. Details are available in the official pricing list.
