BigMemory is described as ': a commercial in-memory data management suite for real-time Big Data applications that stores up to hundreds of terabytes in distributed memory across multiple servers without performance hits from the Java garbage collector' and is a in-memory database in the development category. There are more than 25 alternatives to BigMemory for a variety of platforms, including Linux, Windows, Mac, Web-based and Self-Hosted apps. The best BigMemory alternative is MongoDB, which is free. Other great apps like BigMemory are Redis, CouchDB, Valkey and DiceDB.
