What is a potential downside of using asynchronous replication in EDB Postgres Distributed (BDR)? Increased risk of data loss during a node failure. Reduced read performance due to delayed data propagation. Inability to scale the number of nodes beyond a certain limit. Higher resource consumption due to constant data synchronization. None Show Hint Asynchronous replication can lead to data loss if a node fails before its changes are propagated to other nodes, as there is no guarantee of immediate consistency. 2.

It defines the set of tables and sequences to be replicated across nodes. It logs all data changes made by each node. It tracks the replication lag between nodes.
