## What it is
Infinispan is an open-source, distributed in-memory key/value data grid and NoSQL cloud data store written in Java. It supports embedded and server deployments, full-text and kNN vector search, ACID transactions, cross-site replication, and Redis/Memcached/REST/HotRod client protocols.

## Use cases
- distributed in-memory cache for microservices
- vector store for RAG applications
- semantic caching of LLM responses
- Redis-compatible clustered data store
- session store for Spring Boot or Keycloak
- cross-datacenter replicated key-value store
- full-text and relational querying of in-memory data
- conversation memory for AI agents

## When to choose
- you need an elastically scalable, highly available in-memory data grid on the JVM
- you want a drop-in Redis/Memcached alternative with clustering and failover
- you need a distributed vector database integrated with Spring AI, LangChain4j, or Quarkus
- you require cross-datacenter replication with automatic failover
- you want embedded in-process caching plus a standalone server option

## When to avoid
- you need a simple single-node cache with minimal operational footprint
- your stack is non-JVM and you don't need distributed features — a plain Redis instance may be simpler
- you need heavy analytical or document-database workloads better suited to dedicated NoSQL stores
- you require a fully managed cloud service rather than self-hosted infrastructure
