cbickel opened a new pull request #3747: Memory based loadbalancing URL: https://github.com/apache/incubator-openwhisk/pull/3747 This PR implements the idea, that has been discussed in the following mail thread: https://lists.apache.org/thread.html/dfccf972bc1419fe48dbc23119441108c45f85d53625fd6f8fc04fcb@%3Cdev.openwhisk.apache.org%3E It changes the amount of containers an invoker can spawn based on available memory and not on the CPU. In addition it makes the loadbalancer aware about the amount of available memory on each invoker and it limits the invoker to create only user containers, if there is enough free memory. This PR is WIP. I need to adjust some tests and I need to add some tests for this functionality. ## Related issue and scope <!--- Please include a link to a related issue if there is one. --> - [ ] I opened an issue to propose and discuss this change (#????) ## My changes affect the following components <!--- Select below all system components are affected by your change. --> <!--- Enter an `x` in all applicable boxes. --> - [ ] API - [ ] Controller - [ ] Message Bus (e.g., Kafka) - [ ] Loadbalancer - [ ] Invoker - [ ] Intrinsic actions (e.g., sequences, conductors) - [ ] Data stores (e.g., CouchDB) - [ ] Tests - [ ] Deployment - [ ] CLI - [ ] General tooling - [ ] Documentation ## Types of changes <!--- What types of changes does your code introduce?
