Multi-Master Replication with Conflict Resolution & Avoidance
This SPOCK extension provides multi-master replication for PostgreSQL 14+ We leveraged the BDR2 Open Source project as a solid foundation to build upon for this enterprise-class extension.
Our production version is 3.2 and includes the following important enhancements beyond Spock 3.1:
- Support for pg14
- Support for pg17devel
- Support for Snowflake Sequences
- Support for setting a database to ReadOnly
- Prelim support for Hidden Columns
- A couple small bug fixes from pgLogical
- Native support for Failover Slots via integrating pg_failover_slots extension
