Optimized identification of performance regression

A method, the method comprising:

• deduplicating historical client queries based on a workload selection configuration to determine a grouping of historical client queries;
• generating a workload based on at least a portion of the grouping of historical client queries;
• repeatedly executing a test run of the workload using resources of a cloud environment to determine whether there is a performance difference in the test run;
• in response to determining that there is no performance difference, identifying one or more sets of decreased resources of the cloud environment;
• and
• re-executing the test run using the one or more sets of decreased resources of the cloud environment to determine whether there is a performance difference in the test run that is attributed to the one or more sets of decreased resources of the cloud environment.

A non-transitory computer readable storage media, programmable to execute instructions that, when executed, cause a processor to:

• deduplicate historical client queries based on a workload selection configuration to determine a grouping of historical client queries;
• generate a workload based on at least a portion of the grouping of historical client queries;
• repeatedly execute a test run of the workload using resources of a cloud environment to determine whether there is a performance difference in the test run;
• in response to determining that there is no performance difference, identify one or more sets of decreased resources of the cloud environment;
• and
• re-execute the test run using the one or more sets of decreased resources of the cloud environment to determine whether there is a performance difference in the test run that is attributed to the one or more sets of decreased resources of the cloud environment.
