Hi, Pavel and I are working on lean OpenWhisk. The idea is to allow an efficient use of OpenWhisk with small form factor compute nodes (e.g., IoT gateways). The proposition is to get rid of Kafka, have controller and invoker compiled together into a "lean" controller-invoker (have a Gradle project for that) with controller calling the invoker's method directly via an in-memory object (a queue, which is also loaded via SPI) via a new pluggable load balancer that is selected via SPI using configuration file property setting. Here is a blog https://medium.com/@davidbr_9022/lean-openwhisk-open-source-faas-for-edge-computing-fb823c6bbb9b providing some more detail and points to our fork.
An important thing is that we are _not_ proposing a new project. Rather we want to submit a PR to allow for a lean distro of OpenWhisk that uses the same OpenWhisk code base and consumes everything downstream by virtue of exploiting SPI. Thoughts?
