Oracle Coherence is the world’s first—and the leading—in-memory data grid, with proven robustness and the richest feature set in the market. Designed for data management and grid computing, this cloud-friendly clustered software can be used to scale mission-critical applications, quickly access data while offloading backend systems, implement parallel distributed computing algorithms and event-driven architectures, and store data in microservices and AI applications. Oracle Coherence is a fast, key-value store with optional persistence, offering fault-tolerant automatic sharding, polyglot and REST interfaces, querying, transactions, eventing, and in-place processing, as well as change data capture, multi-site federation, messaging, and integrations with popular frameworks.

JavaOne 2025 marks the return of Oracle’s premier Java developer conference—just in time for
Java’s 30th anniversary. Join a who’s who of Java luminaries as we celebrate with three days of
learning, laughter, and the launch of Java 24.
Coherence is a distributed, in-memory system for storing frequently accessed data that significantly accelerates application performance.
Coherence stores frequently accessed data as serialized key-value pairs in a Java Virtual Machine (JVM) cluster with automatic sharding. Read, query, and write latencies are fast—on the order of 1 millisecond—to achieve maximum application performance and stability.
Union Pacific Railroad built its next-generation logistics platform on Oracle Coherence because the scale of its microservice architecture (20,000 JVMs serving 1.3B calls per day) demanded a highly scalable data management technology.
Overloaded backends cause poor experience and scaling limits. Inject Coherence to relieve load and improve performance.
Coherence’s in-place processing is ideal for data-intensive computation, such as risk analytics in financial services.
With event models, messaging, and integration with Oracle Stream Analytics, Coherence is ideal for event-driven systems.
Coherence’s persistence feature alleviates the need for any other data store needed for state used by microservices.

With a wealth of new features easing development of high-scale mission-critical enterprise applications, Oracle Coherence 14.1.2 has been released. Running on Java 17 and 21, it contains extensive new functionality: overhauled and expanded Spring integration, new gRPC-based polyglot clients, APIs for bootstrapping clients and servers and implementing the Repository pattern from domain-driven design, grid-backed implementations of java.util.concurrent types, numerous operability and observability enhancements, and much more.
