This in-depth feature comparison shows how the most current versions of GridGain Professional Edition, Enterprise Edition, Ultimate Edition and Oracle Coherence (and their respective open source projects where relevant) compare in 25 different categories.
Oracle® Coherence™ is a proprietary an in-memory data grid that is used by companies to scale applications built on an Oracle database. Oracle acquired Tangasol, the company that built Coherence, in 2007 and renamed it Oracle Coherence. The current version is 3.7.1 or Oracle Coherence 12cR2 when combined with Oracle 12.
GridGain®, built on the Apache® Ignite™ open source project, is an in-memory computing platform that includes a distributed in-memory data grid (IMDG), a hybrid SQL and key-value in-memory database (IMDB), a stream processing and analytics engine, and a continuous learning framework for real-time machine and deep learning. It can be used with any RDBMS, NoSQL or Hadoop database. GridGain Systems donated the original code to the Apache Ignite project and is the largest contributor.
Oracle Coherence has many of the core capabilities expected in an IMDG, including the ability to distribute and partition data, and scale out across a cluster. But as an IMDG, the Coherence technology is at the same state as many IMDGs were 5 to 10 years ago. Oracle Coherence 3.7 was released in 2011 and is currently at Release 3.7.1. Not much has been added since 2011 while most leading vendors have significantly evolved their products in the interim. GridGain is better than Coherence in almost every IMDG use case. This is due, in part to the innovation that comes from being built on Apache Ignite, one of the top five Apache Software Foundation open source projects.
