Connecting the Dots: The Path from Document Database to Graph Database

" summary

Compares Cosmos DB and Neo4j migration with concrete results and methods: an T0–T3 live migration that snapshots, bulk migrates, replays change events and flips a flag to cut over with zero downtime; uses Cosmos change-feed and change-event replay to guarantee consistency and enable rollback; data model shifts from entity-centric to property-centric and replaces monolithic reads with short-circuit boolean Cypher queries and Cypher MERGE idempotent writes; scales across 84,000+ sandboxes and 13,000+ orgs, cutting latency from 800ms to 50ms on average.
