⁠Coherence CE (Community Edition) Docker Images

⁠Introduction

Want blazing fast access to terabytes of data? Want to scale across compute resources and harness the power of all your machines? Want comprehensive data reliability in the face of uncontrollable infrastructure faults? You've come to the right place.

Coherence CE (Community Edition)⁠ is a free and open source edition of Oracle Coherence⁠, first and market-leading in-memory data grid. Data grid software is middleware that reliably manages data objects in memory across many servers. By automatically and dynamically partitioning data, it ensures continuous data availability and transactional integrity, even in the event of a server failure.

Since its initial release in 2001, it has been used by hundreds of customers across many industries to power some of the mission critical systems you use every day. It has been used at scale, for both compute and raw storage, in a vast array of industries such as critical financial trading systems, high performance telecommunication products and eCommerce applications. Often imitated, but never duplicated, it is now available for everyone to use free of charge.

⁠Overview

At a high level, Coherence provides an implementation of the familiar Map<K,V> interface but rather than storing the associated data in the local process it is partitioned (or sharded) across a number of designated remote nodes. This partitioning enables applications to not only distribute (and therefore scale) their storage across multiple processes, machines, racks, and data centers but also to perform grid-based processing to truly harness the CPU resources of the machines.

The Coherence interface NamedMap<K,V> (an extension of Map<K,V>) provides methods to query, aggregate (map/reduce style) and compute (send functions to storage nodes for locally executed mutations) the data set. These capabilities, in addition to numerous other features, enable Coherence to be used as a framework for writing robust, distributed applications.
