AKS will be upgrading the KEDA addon to KEDA 2.15 on AKS clusters with K8s versions >=1.31. KEDA 2.15 brings multiple breaking changes. The breaking changes are listed below:

• The removal of Pod Identity support. If you use pod identity, we recommend you move over to workload identity for your authentication.

• The removal of Azure Data Explorer 'metadata.clientSecret' as it was not safe for managing secrets.

• Removal of the deprecated metricName from trigger metadata section. If you are using metricName today, Please use trigger.name to optionally name your trigger.
