Multi-Leader Topologies
Explore the various multi-leader replication topologies used in distributed systems like Apache Kafka. Learn how different configurations such as all-to-all, circular, and star affect data exchange, replication reliability, and conflict resolution. Understand challenges like write ordering and node failures, and discover mechanisms like version vectors to manage data consistency across leaders.
We'll cover the following...
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 ...
