Description

Things like:

  • Could gossip less frequently across DCs.
  • Could prefer own DC when selecting nodes for direct replication.

Contributor guide

Research direction
Study the current gossip protocol and node selection in DistributedData. Identify how to reduce gossip frequency across DCs and prefer local DC for replication. Look into existing network topology awareness mechanisms in Akka.
