Summary

As of March 2019, CockroachDB announced the capability to import MySQL database dump files, facilitating a smoother transition for users migrating from MySQL to CockroachDB, a globally-distributed SQL database. This feature, though initially in beta, allows data from MySQL to be imported with a single command, streamlining the previously cumbersome process of manually specifying schemas due to the limitations of CSV-based imports. The integration involves using an adapted MySQL parser from the Vitess project to translate MySQL dialects into CockroachDB's system, ensuring compatibility with its data types and efficient data distribution across nodes. Despite some known issues, such as difficulties with full-text indexes and certain invalid date values, CockroachDB is confident that this new import functionality will significantly ease the transition for users, evidenced by its successful application in large-scale migrations like Baidu's. Users are encouraged to follow the MySQL migration guide and report any bugs encountered during the process.
