I also updated https://wiki.openstack.org/wiki/DistributedTaskManagement to denote that said wiki is no longer active (it was an attempt to back a taskflow engine[1] with celery); although if u are interested in continuing down this path feel free.

Hopefully that clears up some 'confusion' around that wiki.

So actually they are quite different, (although similar at some level),

Given that celery isn't really a replacement for taskflow although one
could say, from what I've heard from others, that taskflow is a
super-set of what celery is so taskflow likely can replace parts of
celery (but not vice-versa).

Feel free to jump on #openstack-state-management IRC channel if u want
to chat in person more about why (it gets into details that might just
be easier to explain in person).

Hi All,

Please let me know whether celery is replacement for taskflow.

As per my understanding, task-flow can break jobs into tasks and execute
them.

From celery wiki, it also does almost similar behaviour.

I guess in most of openstack components taskflow is widely used.
Any places where its being replaced with celery ??

Celery: https://wiki.openstack.org/wiki/Celery
Distributed: https://wiki.openstack.org/wiki/DistributedTaskManagement
TaskFlow: https://wiki.openstack.org/wiki/TaskFlow

Thanks
Eswar
