MySQL and MariaDB Federated Tables is a storage engine that accesses data from a remote MySQL server or Remote MariaDB Server to edit them as if they were local tables. It provides a way to create virtual tables that act as proxies for tables on another MySQL and MariaDB server, thus enabling distributed queries and enable data integration.

In federated tables, data can be queried and modified without having to replicate the data or transfer it to the local server. Changes to the data in a federated table on the local server are immediately reflected on the remote server. This ensures data consistency between the two servers. Standard SQL queries can be used to retrieve data from federated tables. The local server sends the query to the remote server, which processes it and returns the result set to the local server. Federated tables support insert, update, and delete operations. These operations are performed transparently on the remote server through the Federated table.

When a federated table is created, its structure (column names, data types, constraints) is defined to match the structure of the remote table. The federated table acts as a proxy and represents the remote table on the local server. The user account used to access the federated table must have appropriate permissions on both the local and remote servers. The remote server may need additional permissions to access the remote table.

There are some limitations to be aware of with joined tables. For example, federated table transactions are not supported and the remote table must be accessible and properly configured on the remote server. To create a federated table, specify the FEDERATED storage engine and the remote table connection details in the table definition.

MySQL and MariaDB Federated Tables make sense when storing data from remote MySQL servers in a single database integrated and queried. They provide a convenient way to access and manipulate data in distributed environments without the need for replication or synchronization.
