ClickHouse now supports functioning as a MySQL federated server, enabling it to act as a proxy and integrate with MySQL's federated engine capabilities.
Why it matters
This feature allows ClickHouse to connect to remote MySQL servers using the MySQL federated engine protocol, facilitating seamless data access and integration across MySQL and ClickHouse. It solves the problem of accessing MySQL data through ClickHouse without full data migration, enhancing interoperability and expanding use cases.How to use it
Users can configure ClickHouse as a MySQL federated server by setting up federated tables according to MySQL's federated storage engine specifications. Refer to the official MySQL documentation on federated servers (
https://dev.mysql.com/doc/refman/5.7/en/federated-create-server.html) for instructions on creating federated servers and tables that ClickHouse can interact with.
