Abstract: Systems, methods, and devices for incremental feature development and workload capture in database systems are disclosed. A method includes determining a workload having one or more historical client queries to be rerun for testing the feature, wherein the feature comprises procedural logic. The method further includes executing a baseline run of the workload that does not implement the feature and executing a target run of the workload while implementing the feature. The method further includes comparing the baseline run and the target run to identify whether there is a performance regression in the target run. The method further includes, in response to identifying the performance regression, rerunning the target run to identify whether the performance regression still exists.

Abstract: A system to identify optimal cloud resources for executing workloads. The system deduplicates historical client queries based on a workload selection configuration to determine a grouping of historical client queries. The system generates a workload based on at least a portion of the grouping of historical client queries. The system repeatedly executes a test run of the workload using resources of a cloud environment to determine whether there is a performance difference in the test run. The system, in response to determining that there is no performance difference, identifies one or more sets of decreased resources of the cloud environment. The system re-executes 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.

The system to 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. The system to determine minimum resources of the cloud environment to repeatedly execute the test run using the minimum resources without existence of a performance difference in response to re-executing the test run using the one or more sets of decreased resources of the cloud environment.

Abstract: Systems, methods, and devices for feature release and workload capture in database systems are disclosed. The method includes determining a workload based on one or more client queries to be rerun to test a feature that is unreleased to one or more database clients. The method includes repeatedly executing a test run of the workload to determine a stability factor of the test run. The method includes re-executing, in response to determining the stability factor of the test run, the test run using resources with a different concurrency to confirm the stability factor of the test run. The method includes releasing the feature to the one or more database clients in response to confirming the stability factor of the test run.
