Subject Proposing Lean OpenWhisk
Date Mon, 16 Jul 2018 11:17:00 GMT

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

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.
