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
.
Thank you.

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
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

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

Hi David,
I absolutely agree, this should not be held back. It'd be great if you
could chime in on the
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
d consumes everything downstream by virtue of
exploiting SPI.
Thoughts?
Thanks.
