  • Design for massive concurrency on modern multi-CPU architectures
  • Optimize memory use for increased performance and parallelism
  • Open source, open community, open design

Scope

  • Re-designed modular architecture providing plugins with defined APIs
  • Simple design for ease of use and administration
  • Reliable, ACID transactional

If you like databases and data structure research, now is a wonderful time to be active.
