Currently, Postgres-BDR can be deployed in the all-to-all architecture, which has been tested on clusters of up to 99 master nodes. Each of those nodes is a normal, fully functioning PostgreSQL server that can perform both reads and writes.
Postgres-BDR connects directly between each node, forming a mesh of connections. Changes flow directly to other nodes in constant time, no matter how many nodes are in use. This is quite different from circular replication used by other DBMS.
All Postgres-BDR nodes should have pg_hba.conf definitions to allow paths between each node. It would be easier to have these settings the same on all nodes, but that is not required.
Each node requires an LSR link to all other nodes for each replicated ...
