Couchbase XDCR

A skill for designing and operating Cross-Datacenter Replication between Couchbase clusters.

Distinct from:

• couchbase-app-integration — application code patterns for XDCR-aware reads and writes
• couchbase-migration-execution — one-time migration, not ongoing replication

If the conversation is "I need data in multiple regions" or "how do I keep two clusters in sync," this is the right skill.

When this skill applies

• "How do I replicate between two clusters?"
• "Active-active vs active-passive — which should I use?"
• "How does conflict resolution work in XDCR?"
• "How do I filter which documents get replicated?"
• "How do I monitor XDCR lag?"
• "XDCR replication is behind — how do I diagnose it?"
• "What's the XDCR conflict log in 8.x?"
