Our verdict on Hazelcast Platform
Hazelcast Platform combines a distributed stream-processing engine with an in-memory data store for real-time applications. It is aimed at teams that need streaming and distributed state in one self-managed platform, with support for stream and batch processing, SQL queries, stateful computation, distributed data structures, and external-system connectivity. Deployment options include on-premises, private clouds, public clouds, and Kubernetes-based environments, while supported languages are Java and SQL.
Pricing is structured around two editions. Community Edition is free and includes the stream processing engine, SQL querying, and distributed data storage. Enterprise Edition is a licensed commercial edition with professional support and additional reliability, availability, security, and scalability features. The Security Suite includes role-based access control and TLS encryption. This split gives teams a way to start with core distributed processing and storage, while organizations requiring commercial support or expanded operational capabilities can evaluate the Enterprise tier.
Hazelcast’s strongest category fit comes from combining processing with state and storage rather than treating stream processing as an isolated pipeline. Its Pipeline API supports distributed stream processing, while SQL-based streaming queries provide windowed aggregations. Connectors cover Apache Kafka, JDBC, MongoDB, Amazon Kinesis, Amazon S3, Azure Blob Storage, Google Cloud Storage, Hadoop HDFS, JMS, Apache Pulsar, Redis, PostgreSQL, MySQL, Elasticsearch, and Kafka Connect. WAN replication and multi-cluster synchronization extend its fit for distributed deployments. Teams needing joins, event-time windows, storage, and connector flexibility should consider Hazelcast; teams wanting only a narrowly focused stream processor may prefer a simpler option.
