Yes, I’ll come up with some additional info and a diagram.

Hi, Renat,

Thanks for raising it up!

Does that mean mistral-engine will do the RPC call directly to
mistral-executor after storing the calling information somewhere? I think a
flow chart would be better to explain current problem and your proposal,
and what's more, I personally think it deserves a spec since I see it as a
feature instead of a simple bug.


Cheers,

[openstack-dev] [mistral] Don't use Scheduler to run actions

[Renat Akhmerov]

Hi Team,

I posted a bug [1] at Launchpad that is pretty important for many reasons. I 
tried to put all needed information into
the bug description providing pros and cons of using Scheduler for running 
actions. I short, I’d like to remove
Scheduler from the chain that leads to running an action on executor for 
performance reason (~30% difference
on large workflows, from my experience). I decided to bring it up to a 
discussion here because I may be
missing something and am very interested in your opinions. Please let me know 
if you have any additional
arguments to those I provided in the bug.
