Terracotta has released a new version of its BigMemory caching software, called BigMemory Go, that can store up to 32GB of Java objects on a single server's main memory. And Tokutek has updated it flagship database so that its works more effectively with flash-based SSD storage.

Terracotta is offering BigMemory Go at no charge. Organizations can deploy the software on as many servers as they wish. BigMemory Go is a version of Terracotta's BigMemory, an in-memory database first released in 2010 to 4TB of data in RAM across multiple servers.

Unlike BigMemory itself, which was recently renamed BigMemory Max, a single BigMemory Go data cache cannot run across multiple servers. The company has released this version to provide existing users of the company's Ehcache open source enterprise Java caching software with an easy migration path to BigMemory, according to Gary Nakamura, general manager of Terracotta.

Ehcache, which Terracotta has estimated to have over 500,000 users, has a limit on the amount of material of that can be stored in memory, due to the limits of Java itself. Most Java applications have a limit of about 4GB to 6GB that can be stored in working memory without significant tuning. BigMemory Go will give Java-based enterprise applications much more room to store data in memory. Terracotta is betting that, over time, enterprise applications will grow so large that they will need to store data across the memory of multiple servers and will need BigMemory Max.
