Microsoft Azure WebJobs SDK Kafka Extension - This library is supported in the Premium Plan along with support for scaling as Go-Live - supported in Production with a SLA. It is also fully supported when using Azure Functions on Kubernetes where scaling will be handed by KEDA - scaling based on Kafka queue length. It is currently not supported on the Consumption plan (there will be no scale from zero) - this is something the Azure Functions team is still working on.
