Architectural Flexibility and Geo-Specificity with Cluster-to-Cluster Replication

on YouTube ↗32m

" summary

YugabyteDB’s xCluster implements tablet-level asynchronous replication between independent universes with uni‑ and bi‑directional modes (active‑passive xClusterDR and active‑active via two uni streams), offers automated switchovers/failovers through Yugabyte Anywhere with bootstrapped reverse replication (no full backup when in‑sync), uses an xCluster safe time to bound potential data loss (demo shows 774 ms potential data loss), resolves conflicts with last‑writer‑wins timestamp ordering, supports multi‑cloud/Kubernetes/on‑prem, and previews automatic DDL replication (preview 2025, 2.25).
