High Availability and Scalability Services for Databases

Continuent.org Projects


  • Sequoia: high availability middleware layer, core controller, JDBC driver, text management console, documentation and more. Sequoia is a continuation of the C-JDBC project. As a result, the migration should be seamless for current users and contributors.

  • Hedera: a modular wrapping of group communications. Current wrappers include Appia, JGroups and Spread.

  • Appia: a group communication implementation usable with Hedera.


  • Bristlecone: Performance testing tools for scale-out architectures.

  • Carob: a C++ client library and API that implements the Sequoia protocol with the controller and an ODBC driver for Sequoia. (Deprecated--use Myosotis instead.)
