Abstract
A replicated key-value store is implemented using a 'last-write-wins' consensus protocol. To improve throughput and latency in cross-data-center configurations, a system deploys a cross-cluster, learner-only member to a cluster of nodes (e.g., a data center). The cross-cluster, learner-only member submits key-values received at local leader members to remote clusters. Conflicts between the key-values and initial values at the remote clusters are resolved using a 'last-write-wins' consensus protocol.
