Multi-Leader Topologies
Explore various multi-leader topologies used in data replication within distributed systems. Understand how nodes exchange writes across all-to-all, circular, and star configurations and the trade-offs such as data consistency, latency, and failure resilience. Learn how mechanisms like version vectors help resolve write conflicts and enable causal tracking of data changes.
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 ...
