Backend Multi

class designate.backend.impl_multi.MultiBackend(central_service)

Bases: designate.backend.base.Backend

Multi-backend backend

This backend dispatches calls to a master backend and a slave backend. It enforces master/slave ordering semantics as follows:

Creates for tsigkeys, servers and domains are done on the master first, then on the slave.

Updates for tsigkeys, servers and domains and all operations on records are done on the master only. It’s assumed masters and slaves use an external mechanism to sync existing domains, most likely XFR.

Deletes are done on the slave first, then on the master.

If the create on the slave fails, the domain/tsigkey/server is deleted from the master. If delete on the master fails, the domain/tdigkey/server is recreated on the slave.
