Poolmgr needs to know usage statistics for a function's pod. This change asynchronously taps poolmgr API when router uses a service. Poolmgr can use this information to control pod expiry. It may also be useful later as one of the metrics for autoscaling.
Fission
Fission is a fast serverless framework for Kubernetes with a focus on developer productivity and high performance.
It's heavily customizable (but with sensible defaults), extensible to any language, and interoperates well with other infrastructure.
You can create and edit functions throughs a web UI, or you can use your favorite editor and upload them using a CLI. You can trigger these functions via HTTP requests to paths, or by timers.
Try it out at http://demo.example.com
Running Fission
On your own Kubernetes cluster
Setup Kubernetes
https://github.com/kubernetes/minikube
Get and Run Fission
$ wget http://example.com/fission.yaml $ kubectl create -f fission.yaml
Status
Fission is in early alpha.
Performance
The goal is to have less than 1 second latency for requests that don't have a running instance. In practice, benchmarks show this latency at TODO msec for the NodeJS environment.
Here's a simple hello world benchmark on NodeJS: TODO. It achieves TODO requests per second on a TODO-node Kubernetes cluster.
