add additional connections to the mesh network so they are not included in the
32 node recommendation.

BDR currently has hard limit of no more than 1000 active nodes as this is the
current maximum Raft connections allowed.

BDR places a limit that at most 10 databases in any one PostgreSQL instance
can be BDR nodes across different BDR node groups. However BDR works best if
only one BDR database per PostgreSQL instance is used.

- BDR can run hundreds of nodes assuming adequate hardware and network. However, for mesh-based deployments, we generally don’t recommend running more than 48 nodes in one cluster. If extra read scalability is needed beyond the 48 node limit, subscriber only nodes can be added without adding connections to the mesh network.

- The minimum recommended number of nodes in a group is three to provide fault tolerance for BDR's consensus mechanism. With just two nodes, consensus would fail if one of the nodes was unresponsive. Consensus is required for some BDR operations such as distributed sequence generation. For more information about the consensus mechanism used by EDB Postgres Distributed, see [Architectural details](/pgd/4/architectures/#architecture-details).
