Computer data communications in a high speed, low latency data communications environment

An apparatus for computer data communications in a data communications environment, the apparatus comprising:

• one or more computer processors;
• one or more computer memories operatively coupled to the one or more computer processors, the computer memories configured to store computer program instructions configured to:
• issue a request, from an application of a contributing client device to a stream administration server, to contribute messages from the application to a feed adapter within a data communication environment via a message stream which bypasses the stream administration server, wherein,
• the feed adapter is coupled to a feed source via a feed adapter input stream and to at least one subscribing device via a feed adapter output stream,
• the feed source is separate from the contributing client device, and
• the feed adapter input stream is separate from the message stream;
• receive, in response to the request and an authentication of the contributing client device,
• a set of constraints on messages to be transmitted from the contributing client device to the feed adapter, wherein the set of constraints specifies one or more topics of messages that the contributing client device is authorized to contribute to the feed adapter;
• establish the set of constraints in a messaging middleware of the contributing client device;
• receive, in the messaging middleware of the contributing client device from the application of the contributing client device, a message for transmission to the feed adapter on the message stream;
• determine, by the messaging middleware of the contributing client device, whether contents of the message satisfy the set of constraints, wherein the determine comprises:
• compare a topic associated with the message with the one or more topics of messages that the contributing client device is authorized to contribute to the feed adapter;
• and
• administer the message, by the messaging middleware of the contributing client device, in dependence upon whether the message satisfies the set of constraints.

A computer program product for computer data communications in a data communications environment, the computer program product disposed upon a non-transitory machine-readable storage recordable medium, the computer program product comprising computer program instructions configured to:

• issue a request, from an application of a contributing client device to a stream administration server, to contribute messages from the application to a feed adapter within a data communication environment via a message stream which bypasses the stream administration server, wherein,
• the feed adapter is coupled to a feed source via a feed adapter input stream and to at least one subscribing device via a feed adapter output stream,
• the feed source is separate from the contributing client device, and
• the feed adapter input stream is separate from the message stream;
• receive, in response to the request and an authentication of the contributing client device,
• a set of constraints on messages to be transmitted from the contributing client device to the feed adapter, wherein the set of constraints specifies one or more topics of messages that the contributing client device is authorized to contribute to the feed adapter;
• establish the set of constraints in a messaging middleware of the contributing client device;
• receive, in the messaging middleware of the contributing client device from the application of the contributing client device, a message for transmission to the feed adapter on the message stream;
• determine, by the messaging middleware of the contributing client device, whether contents of the message satisfy the set of constraints, wherein the determine comprises
• compare a topic associated with the message with the one or more topics of messages that the contributing client device is authorized to contribute to the feed adapter;
• and
• administer the message, by the messaging middleware of the contributing client device, in dependence upon whether the message satisfies the set of constraints.
