Re: Pausing actions, waiting for human input etc.

Hi Bertrand, AFAIK, this is not currently possible out of the box, but it will be very useful. At IBM Research -- Haifa, we are thinking about similar functionality for long-running serveless pipelenes over a data lake. I think a generalization of this will be a "state machine", where you can

Re: Proposal on a future architecture of OpenWhisk

Hi Markus, I'd like to better understand the edge case. Citing from the wiki. >> Edge case: If an action only has a very small amount of containers (less than there are Controllers in the system), we have a problem with the method described above. Isn't there always at least one controller

Re: Proposing Lean OpenWhisk

Hi Dominic, Lean OpenWhisk is not supposed to run on the IoT devices such as sensors and actuators directly. It's supposed to run on a Gateway node that controls the sensors and actuators connected to it. Think AWS GreenGrass, Azure Functions on IoT Edge. This is the same use case. The data

Re: System overflow based on invoker status

Hi Rodric, An alternative way of doing what you propose might be using Kingman's approximation which explicitly connects expected wait time in a queue with utilization, mean service time and COVs in interarrival and service times. It's specifically geared for highly loaded system (the case

Re: Proposing Lean OpenWhisk

Hi Markus, Thanks for the prompt response and the pointer to your proposal. Indeed, there is a synergy between this Lean OW proposal and the more far fetching changes that you suggest. The similarity is that Invoker's role is basically being done by controller with no Kafka in between to
