KEDA Durable Functions Scaler is an extension that is enable us to autocale Durable Functions deployed on Kubernetes cluster. This extension uses External Scaler Support for KEDA.
The key features of KEDA Durable Functions Scaler are:
- Intelligent Auto Scaling
- One-liner deployment using Helm
KEDA supports multiple scalers. As a part of the scalers, this project support Durable Functions Scaler for KEDA. You can deploy Durable Functions with auto scale feature on Kubernetes.
KEDA Durable Functions Scaler works as a gRPC server of the External Scaler Support.
- gRPC services with ASP.NET Core
- Watch Control/Worker queues by DurableTask and use Scale Recommendation
- Get the current worker count from Kubernetes API Server
Currently, KEDA Durable Scaler can't make functions scale down to zero. Minimum pod number is one. Durable Scaler need to send data to control/worker queue. For achieve this behavior, we need to separate the HTTP and non-HTTP deployments. However, the feature seems not working. We need to wait until this issue is fixed.
- Add configuration for enabling only HTTP or only non-HTTP functions #4412
- Pods doesn't scale in to zero #17
