Move separate caches to one cache -- functionServiceCache. It can be looked up by function, can update atime by address, and can be deleted by podname. This removes the other caches. Some of the concurrency logic is still a bit hairy; it might be better not to use fission.Cache.
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.
