Maintaining stream processing resource type versions in stream processing

A computer program product for maintaining version consistency of stream processing applications, the computer program product comprising:

• one or more computer-readable storage media, and program instructions stored on the one or more computer-readable storage media, the program instructions comprising:
• program instructions to receive a submitted request to run a job, wherein the job includes a processing element and a timestamp associated with running the job;
• program instructions to identify a resource type, based on a tag included in the job;
• program instructions to determine a version of the resource type associated with the processing element, based on a mapping of the tag and the timestamp;
• program instructions to request from a resource manager, assignment of a resource of the version of the resource type to the processing element;
• and
• responsive to a confirmation from the resource manager of assignment of the resource of the version of the resource type to the processing element, program instructions to cause the process element to perform an operation using the resource of the version of the resource type assigned by the resource manager.
