--------------------------------
HI [[email protected]]
Thanks for posting the thoughts here.
I think we must have an additional check based on start name. However I am
skeptical with name based sorting comparison.
An ideal FIFO is always first in first out, where first submitted app should
get preference. Priority is an anti pattern to this FIFO, however based on the
use case which we had, we made a behaviour change to add priority as a first
check. To me priority > submit time / start time seems good condition for now.
