The scheduler has been pretty error-prone and hard to work on, and I feel like there may be a dwindling core of active experts. I'm sure its very discouraging to folks trying to make what seem like simple changes, and then find they are in a rats nest of complex issues they weren't expecting. But for those who are still trying, THANK YOU! more involvement and more folks becoming experts is definitely needed.
I put together a doc going over the architecture of the scheduler, and things I've seen us get bitten by in the past. Its sort of a brain dump, but I'm hopeful it'll help orient new folks to the scheduler. I also hope more experts will chime in -- there are places in the doc I know I've missed things, and called that out, but there are probably even more that should be discussed, & mistakes I've made. All input welcome. https://docs.google.com/document/d/1oiE21t-8gXLXk5evo-t-BXpO5Hdcob5D-Ps40hogsp8/edit?usp=sharing
