Stream Scalability

To be able to deploy a successful distributed stream application,
there are 4 pillars

• the business functionality: implemented using the Nuxeo Stream processor
• the instrumentation plane: metrics and observability, proving that the job is done
• the control plane: how to scale up and down.
• the operation plane: how errors are handled.

Most of the stuff is there but there are some missing details to reach this:

• be able to scale up or down on a specific computation inside a processor
• be able to stop a Nuxeo instance when a processor is starving to ease the scale down

Creating a small POC to demoing these aspects will enable to identify the missing part and can be used as a playground for training
