Workload management

A computer program product comprising a computer readable hardware storage medium for operating a messaging system, the messaging system comprising a plurality of connected components, the computer program product comprising instructions, embodied on the computer readable hardware storage medium, which when executed on the messaging system, cause the messaging system to:

• collect one or more performance metrics for one or more components of the messaging system wherein the messaging system comprises a schema defining fields for messages including at least one field defined as non-essential;
• and
• responsive to determining that at least one performance metric has crossed a predetermined threshold, inform the one or more components of the messaging system that a surge in workload has occurred,
• wherein, responsive to being informed, the informed components remove non-essential fields from transmitted messages, and wherein at least one non-essential field removed from the transmitted messages includes data values.

A messaging system comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• collect one or more performance metrics for one or more components of the messaging system wherein the messaging system comprises a schema defining fields for messages including at least one field defined as non-essential;
• and
• responsive to determining that at least one performance metric has crossed a predetermined threshold, inform the one or more components of the messaging system that a surge in workload has occurred,
• wherein, responsive to being informed, the informed components remove non-essential fields from transmitted messages, and wherein at least one non-essential field removed from the transmitted messages includes data values.
