MOLT: A Toolkit for Migrations You Can Trust
Blog post from Cockroach Labs
Migrating databases to CockroachDB is facilitated by the MOLT (Migrate Off Legacy Technology) toolkit, which aims to minimize downtime and ensure data correctness throughout the process. MOLT is a comprehensive, modular system designed to address the complexities of real-world migrations, providing tools such as MOLT Convert for schema translation, MOLT Fetch for bulk data transfer, MOLT Replicator for ongoing data synchronization, and MOLT Verify for final data verification. Each tool in the MOLT suite operates independently but can be integrated to form a robust migration pipeline, allowing teams to adapt based on their specific environment and risk tolerance. By addressing common challenges like downtime, schema drift, and data mismatches, MOLT offers a streamlined and iterative approach to database migration, enabling enterprises to transition to CockroachDB with greater confidence and reduced risk.
