In-Memory Distributed Database
What is Infinispan?
Open-source, distributed, in-memory database with full-text and vector search. Elastically scalable, highly available, and replicated across data centers. Connect via HotRod, REST, Redis, or Memcached protocols.

Get Started NowFeatures
Interoperability
Access data across multiple protocols and programming languages.
Resilient and Fault Tolerant Data
Ensure data is always available to meet demanding workloads.
ACID Transactions
Guarantee that data is always valid and consistent.
Clustered Processing
Process data in real-time without burdening resources.
Queries & Vector Search
Full-text, relational, and kNN vector similarity search for AI and traditional workloads.
Boost Application Performance
Infinispan turbocharges applications by storing data closer to processing logic, which reduces latency and increases throughput.
Available as a Java library, you simply add Infinispan to your application dependencies and then you’re ready to store data in the same memory space as the executing code.
If you want to provision a data layer that is independent of your applications, you can use Infinispan Server for remote access to data with in-memory performance. Clients are a single network hop away from data through consistent hashing techniques and can make requests over HTTP or with a custom binary TCP protocol called Hot Rod.

Infinispan provides trusted open-source technology to deliver scalability to meet workload demands and reduce resource utilization. At the same time, Infinispan distributes your data across clusters so no single point of failure causes data loss.
One popular use for Infinispan is as a shared store for stateful data, such as user HTTP sessions. Applications can stay lightweight and avoid heap usage by externalizing sessions to Infinispan clusters, which act as an independent data layer.

Backup Across Data Centers
Infinispan clusters running in different geographical locations can form global clusters to back up your data across sites. If sites go offline clients can immediately switch to an available cluster, making sure data center faults do not cause service interruptions.
When using the Infinispan Operator with Kubernetes environments such as Red Hat OpenShift, cross-site replication capabilities make your data ready for hybrid and multi cloud deployments.
Infinispan also guarantees data consistency when using cross-site replication, even in cases where clients make concurrent writes at different locations that use asynchronous replication. So your data is always there and always accurate, no matter where you’re running.
