Hi,

Can somebody please help me understand the difference between UDR and BDR with examples?

BDR is for multiple masters that all replicate to each other.

UDR takes data from one server and copies it to another. One way. (By the way, I strongly advise you to now use pglogical instead of UDR).

BDR:

A <==> B

UDR/pglogical:

A ==> B
