In a multi-master replication setup, what is the impact of network latency on EDB Postgres Distributed (BDR)?

Network latency has no impact as all operations are local to each node.

Network latency only affects read operations, not write operations.

Network latency is automatically mitigated by the BDR's internal algorithms.

Increased network latency can lead to higher conflict rates and slower replication.

None

Network latency can increase the time it takes for changes to propagate between nodes, potentially leading to higher conflict rates and slower replication.

What is the role of conflict resolution in EDB Postgres Distributed (BDR) multi-master replication?

To ensure that all nodes have the same configuration settings.

To prevent data loss during node failures.

To optimize query performance across the cluster.

To resolve data conflicts that occur when the same data is modified on multiple nodes.

None

Conflict resolution is crucial in multi-master replication to handle scenarios where the same data is modified on different nodes, ensuring data consistency.
