Multi-Leader Topologies

Multileader architectures come in different topologies. A replication topology refers to how nodes in a system are set-up to exchange local writes, i.e. writes at a given leader, with other leader nodes.

The case of two nodes is trivial as the information must be exchanged bilaterally, however, with three or more nodes the number of possible ways nodes can exchange information among themselves is numerous. We’ll discuss the various topologies in which nodes can be arranged to exchange writes with each other.
