MOLT goes live: Migrating to CockroachDB with minimal downtime
summary
Demo shows three migration paths — offline, immediate, and consistent — and specific tools: schema converter MOLT STCT, bulk loader MTT Fetch, and the MOLT Live Migration Service as a proxy layer. The live demo uses CDC Sync to replicate changes, runs behind 3 proxies and drains 64 connections from MySQL, causing a short latency spike (~30–45s) while queued requests switch to CockroachDB; the cutover completes successfully in the demo.
