What is STACKIT Key Value Store?
STACKIT Key Value Store provides fully managed instances of the open source non-relational key value store Valkey. Valkey is a Linux Foundation project and works as an in-memory database with microsecond response times. STACKIT handles provisioning, operations, and maintenance of the instances.
The service has been generally available since 1 August 2026 and succeeds STACKIT Redis, which was deprecated on the same date. Final decommissioning of all Redis instances is scheduled for 1 August 2027, so existing Redis workloads should be migrated in good time.
Core Features
- In-memory architecture: Microsecond response times for caching and session scenarios
- Rich data types: Strings, lists, sets, sorted sets, hashes, bitmaps, HyperLogLogs, and streams
- Persistence: Snapshots (RDB) and append-only files (AOF)
- High availability: Replica-set plans with three nodes across multiple availability zones and automated failover
- Messaging: Pub/sub and streaming capabilities for service-to-service communication
- Eviction policies: LRU, LFU, and TTL for controlled memory behavior
- Security: TLS encryption and network-level access control lists (ACLs)
Typical Use Cases
Caching for web and API applications: Frequently requested results are kept in memory, reducing load on backend databases.
Session storage: Distributed applications store user sessions centrally so requests can be served regardless of the instance handling them.
Pub/sub and streams: Services exchange events over publish/subscribe channels or streams without operating an additional messaging platform.
Redis migration: Existing Redis workloads can be moved to Key Value Store before the Redis instances are shut down.
Benefits
- Sovereign operation: Managed service within the STACKIT cloud
- Clear successor path: Defined migration route away from the deprecated Redis offering
- Open technology: Valkey is open source, with no proprietary lock-in
- Production-ready plans: Replica sets across multiple availability zones with automated failover
- Automatable: Provisioning via API, Terraform, and Cloud Foundry

Frequently Asked Questions
What is STACKIT Key Value Store?
STACKIT Key Value Store provides fully managed instances of the open source non-relational key value store Valkey. STACKIT handles provisioning, operations, and maintenance.
Is the service compatible with Redis?
Valkey is an open source fork of Redis and supports the same data types, including strings, lists, sets, sorted sets, hashes, bitmaps, HyperLogLogs, and streams. STACKIT deprecated Redis on 1 August 2026 and positions Key Value Store as its successor; final decommissioning of all Redis instances is scheduled for 1 August 2027.
How is high availability achieved?
Replica-set plans consist of three nodes distributed across multiple availability zones and perform automated failover. Single-node plans do not provide this level of high availability, and STACKIT strongly advises against using them in production environments.
Is data persisted?
Yes. The service supports snapshots (RDB) and append-only files (AOF). Instances can also be backed up and restored; the official documentation describes the exact procedures.
How does the service integrate with existing environments?
Instances are provisioned through the STACKIT Portal or the API. A Terraform provider is available for infrastructure as code, and the service can be used as a backing service in Cloud Foundry.
