Variable selection of different versions of an event handler

A data processing system adapted for variable event handling in a multi-tenant environment, the system comprising:

• a host computing platform comprising one or more computers, each comprising memory and at least one processor;
• and,
• a variable event handling module comprising computer program instructions enabled while executing in the host computing platform to perform:
• receiving an event placed on an event bus in an event driven data processing system, the event corresponding to a multiplicity of different instances of a single event handler, each instance being adapted to process the event;
• decoding the event to identify a version of a target application for the event;
• matching the version of the target application to an end point for a particular one of the different event handlers;
• and,
• routing the event to the matched end point.

A computer program product for variable event handling in a multi-tenant environment, the computer program product including a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method including:

• receiving an event placed on an event bus in an event driven data processing system, the event corresponding to a multiplicity of different instances of a single event handler, each instance being adapted to process the event;
• decoding the event to identify a version of a target application for the event;
• matching the target application to an end point for a particular one of the different event handlers;
• and,
• routing the event to the matched end point.
