Specific characteristics

Hazelcast is an in-memory computing platform that runs applications with extremely high throughput and low latency requirements. It offers speed, scale, simplicity, resiliency, and security in a distributed architecture. It is comprised of an in-memory data grid and a distributed stream processing engine that work together to run many types of data processing workloads. The data grid (IMDG) pools RAM together across a cluster to deliver data accesses faster than in-memory databases. The stream processing engine (Jet) offers higher throughput and lower latency than other popular stream processing engines.

Hazelcast is open source software available for download at hazelcast.org. Hazelcast also provides an enterprise version that adds advanced levels of capabilities around business continuity, security, and scalability.

Competitive advantages

Hazelcast has an optimized, multi-threaded architecture that enables the highest throughput and lowest latency at scale in data processing applications. The documented benchmarks show its advantage over similar technologies. Hazelcast also offers a significant performance advantage in data processing pipelines, thanks to the tight integration of in-memory storage with a high-speed stream processing engine.

Hazelcast also provides:

  • Comprehensive object storage support, including storage/querying of JSON documents and in-memory streaming/messaging capabilities
  • Jepsen Test-verified strong consistency with its “CP Subsystem”
  • Performance optimizations such as near-cache in which data is stored in a node local to the application to boost speed by reducing network hops
  • Built-in security features including pluggable authentication, role-based access controls, and encryption (at-rest and in-motion)
  • “Embedded mode” which allows easy deployment with applications that auto-discover each other to form the cluster
  • Business continuity capabilities (e.g., active-active and active-passive WAN replication, automatic failover, blue-green deployments, rolling upgrades, job upgrade, hot restart) to minimize both planned and unplanned downtime
  • Data persistence to quickly repopulate the in-memory store during node restart
  • Intel Optane DC Persistent Memory support to realize lower TCO compared to DRAM, as well as faster node restart times from persistent store usage
