Method, device, apparatus of federated computing, and storage medium

A method of federated computing, comprising:

• acquiring a plurality of metadata from a coordination node, wherein the plurality of metadata are uploaded to the coordination node by a plurality of computing nodes, and the metadata of each computing node indicates features of data in a data warehouse of an associated computing node;
• determining, from the plurality of computing nodes, a computing node that executes a first federated computing task cooperatively, as a data provider node, according to the plurality of metadata;
• submitting the first federated computing task to the coordination node, so that the coordination node splits the first federated computing task into a plurality of first subtasks;
• and
• receiving at least one first subtask in the plurality of first subtasks from the coordination node, and executing the at least one first subtask in cooperation with the data provider node.

A device of federated computing, comprising:

• a metadata management module configured to acquire a plurality of metadata from a plurality of computing nodes and publish the plurality of metadata, wherein the metadata indicates features of data in a data warehouse of the computing node;
• a node determination module configured to determine, from the plurality of computing nodes, at least two computing nodes that agree to execute a federated computing task, wherein the at least two computing nodes are computing nodes that agree to execute the federated computing task based on the plurality of metadata;
• a task processing module configured to receive the federated computing task submitted by at least one of the at least two computing nodes, and split the federated computing task into a plurality of subtasks;
• and
• a task distribution module configured to distribute the plurality of subtasks to the at least two computing nodes so as to execute the plurality of subtasks between the at least two computing nodes.
