PrimeBase XT Storage Engine
From Big Database List
PrimeBase XT (PBXT) is a transactional storage engine for MySQL. Tables that use the PBXT Storage engine have the following features:

- Transactional: support for BEGIN, COMMIT and ROLLBACK and recovery on startup.
- ACID compliant: Atomic, Consistent, Isolated, Durable (once committed changes cannot be lost).
- Row-level locking: updates use row-level locking allowing for maximum concurrency.
- Deadlock detection: immediate notification if client processes are deadlocked.
- Referential Integrity: foreign key support.
- Write-once: PBXT avoids double-writes by using a log-based architecture.
