rbradyjpeeler: doesn't validate.  s/zaqar-notify/zaqar_notify/.  Also some white space would be nice for readability. see https://review.openstack.org/#/c/300200/9/workbooks/baremetal.yaml.  I started to test more thoroughly, but I need to build a deploy a new tripleo env01:43

rakhmerovkong: well, ideally we still need to fix the branch04:05
rakhmerovit's still not ok04:05
rakhmerovkong: e.g. https://review.openstack.org/#/c/316481/04:06

mflobomgershen, there is connection, because the workflow itself is executed, but the execution (in execution list) never finish due to an ActionNotFound exception in the engine06:20

Bogeyi'm trying to figure out if mistral is right for my task, or SWF, or if workflow management is even the right conceptual solution to my problem, which is:13:36
Bogeyneed to process high volumes of audio files through several successive steps before they come to rest in storage13:37
Bogeyand need good visibility into where any given file is in the series of steps13:37

openstackgerritRenat Akhmerov proposed openstack/mistral: Refactoring workflow handler  https://review.openstack.org/32369714:00
rakhmerovBogey: at first glance, looks like it's ok to use workflow14:01
rakhmerovif you need state management then it's the right choice IMO14:01
rakhmerovI mean state management for your tasks that the whole process consists of14:02
Bogeyis there a conceptual alternative to workflow that i should be considering?  something like an agent model where there is no "orchestrator" per se?14:03
rakhmerovBogey: well, an obvious alternative is just to use plain Python or some other lang but you'll be missing a bunch of things like state management, HA, scalability etc14:05
rakhmerovsometimes it's ok if your processes are not so long14:05
Bogeyright right, i think i can build this myself but would prefer not to.  what is making me look for alternatives is that there seem to be only a small handful of tools like mistral (SWF being one), and ...14:06
rakhmerovand/or you're running a control logic on a very reliable host (which is typically a bad assumption)14:06
Bogeywhen i see only a small handful of tools, i ask myself if maybe there's some other kind of solution that everyone else is using14:07
rakhmerovwhat do you call SWF? Amazon SWF?14:07
Bogeyyes14:07
rakhmerovyeah, you can use SWF, it's obviously more stable but slightly tricky14:07
rakhmerovMistral is very simple from user perspective14:08
Bogeyand i can't put it on premise14:08
rakhmerovok14:08
rakhmerovif you decide to learn Mistral pls feel free to talk to us here14:09
Bogeysounds great, thanks for your help14:09
rakhmerovwe'll try to guide you through14:09
rakhmerovyou're welcome :)14:09

wolfson292Are there any posted benchmarking results of Mistral. I see documentation on how to benchmark it, but not actual results. Curious of performance at say 1 million tasks a day, with 20 or so steps each.14:57

rakhmerovwolfson292: nope, we don't have such results. Some of our production users may15:13
rakhmerovthis also depends on particular cases, Mistral topology etc.15:14
wolfson292Understood. SWF is very interesting to us, but being tied to the cloud obviously has limitations in certain restricted environments.15:15
wolfson292Mistral seems like the most mature alternative.15:15
wolfson292If you want language/platform independence15:15
