The MySQL Datacontroller storage engine for the MySQL relational database management system is a storage engine which allows a user to create a table that is a local representation of a foreign (remote) table. The foreign table can be located into another storage engine like Oracle or Microsoft SQL Server (MSSQL).
Each cell of a bigtable can have zero or more timestamped versions of the data. Another function of the timestamp is to allow for both versioning and garbage collection of expired data. Tables are split into multiple tablets – segments of the table are split at certain row keys so that each tablet is a few hundred megabytes or a few gigabytes ...
It uses the MySQL client library API as a data transport, treating remote tables as if they were located on the local server. Each Federated table that is defined there is one .frm (data definition file containing information such as the URL of the data source). The actual data can exist on a local or remote MySQL instance.
SELECT list is the list of columns or SQL expressions to be returned by the query. This is approximately the relational algebra projection operation. AS optionally provides an alias for each column or expression in the SELECT list. This is the relational algebra rename operation. FROM specifies from which table to get the data. [3]

It can be used independently of a MySQL Server with users accessing the Cluster via the NDB API (C++). "NDB" stands for Network Database. From the MySQL Server perspective the NDB Cluster is a Storage engine for storing tables of rows. From the NDB Cluster perspective, a MySQL Server instance is an API process connected to the Cluster. NDB ...
