Hazelcast Platform vs Infinispan

Hazelcast Platform brings a distributed compute engine and an in-memory data store together for real-time and AI-driven applications. It can process streaming data before storage, supporting action on data in motion, and provides fast reads and writes for interactive request/response workloads. SQL processing, stateful processing, event-time windows, and Java and SQL are listed capabilities. WAN Replication synchronizes clusters and supports automatic failover to a secondary cluster for disaster recovery. Security features include JAAS role-based access controls and TLS encryption for data moving between nodes and applications. The platform runs on public and private clouds, is available through AWS, Google Cloud, and Azure marketplaces, and supports hybrid deployment. Its Kafka Connector processes Apache Kafka topic streams and sends processed data back to Kafka. Hazelcast identifies mission-critical, data-intensive AI workloads as a focus, including use in financial services, retail, supply chain, and healthcare. The platform is available for Linux, macOS, and Windows, as well as through an API and self-hosted deployment. A free plan and free 30-day Enterprise trial are listed; the trial requires a requested license key. The annual self-managed subscription includes professional support, with pricing available by request.

Infinispan is a free, open-source distributed in-memory database that combines caching with full-text and vector search. Its search capabilities include distributed vector indexes, kNN similarity queries, semantic search, retrieval-augmented generation, and semantic caching. Applications can connect through Hot Rod, REST, Redis, or Memcached, with listed client libraries for Java, Go, JavaScript, C++, .NET, and Python. It can run as an embedded library, standalone server, or container image. Deployment options include a Kubernetes Operator and container images on OpenShift, AWS EC2, Azure, and GCP. Listed cache stores include filesystem, JDBC, SQL, RocksDB, and remote Infinispan clusters. Security features include role- and permission-based access control, security realms, and encryption for inter-cluster traffic and remote endpoints. It supports distributed transactions with optimistic or pessimistic locking, configurable isolation levels, and XA recovery. Native integrations listed include Spring AI, LangChain4j, LangChain, and Quarkus LangChain4j. Infinispan is released under the Apache 2.0 license. Its support policy covers only the latest minor release of a major version, with full, limited, and limited-client support distinctions.
