PostgreSQL: Features new in 7.4: Commercial level asynchronous master-slace replication
- eRServer: Donated by PostgreSQL, Inc (www.pgsql.com)
- Asynchronous: not real time
- Designed for high availability/continuity
- Can be used for performance for some applications
- Has been used by .org registrars (now using latest version, not (yet) open)
- Supports multiple slaves
- Logs updates to selected tables and pushes updates out to slaves
- Problems:
- Not integrated into native code
- Mostly written in Java (requires additional admin, etc)
- Doesn't meet all replication requirements
