Coherence (Oracle Coherence) is an in-memory data grid product that stores and replicates data in a distributed manner across the memory of multiple servers. It caches frequently read data to reduce database load, and provides high availability by continuing service from replicas even when a node fails. It is mainly used in large-scale Java-based enterprise systems.
