Terracotta DB is a distributed in-memory data management solution for both operational storage and analytical processing.  Terracotta DB has powerful query and computation capabilities, leveraging native JDK features such as Java Streams, collections, and functions. It supports the following sub-systems:

  • A storage sub-system fronted by TCStore API

  • A caching sub-system fronted by the next generation Ehcache API which includes and extends JSR 107

Both sub-systems are backed by the distributed Terracotta Server, which provides a common platform for distributed in-memory data storage with scale-out, scale-up and high availability features.

  • Azure certification as a supported platform for Terracotta DB deployments.
