I am pleased to announce the first beta release of Golconde, 0.4.
Golconde is a queue based replication solution for PostgreSQL written in Python 2.6.
It is designed to be loosely coupled and rely upon existing enterprise messaging systems that have STOMP protocol support. Designed to scale easily and with multi-data center implementations in mind, the application and message queues for distribution live outside of the database. By decoupling Golconde from PostgreSQL it is differentiated from existing replication solutions, moving the workload from the database tier, where CPU, RAM and IO overhead can be very expensive, to a commodity layer where the operational cost for performing the data distribution work is much less expensive. In a typical Golconde target database, the PostgreSQL operational overhead is similar to the canonical database write workload.
