## hub-and-spoke architecture

right now I have 2 types of operations, immediate mode and async.
|
||||
|
||||
both types of operations do assignment synchronously. so if the system cant assign the operation to one or more hosts (spokes),
|
||||
or whatever the operation requires, then it will fail.
|
||||
|
||||
some operations tolerate partial failures, like, capacity_avaliable will succeed if at least one spoke succeeds
|
||||
for immediate mode, assignment and completion of the operation (like `list`, `capacity_avaliable`, `destroy`) are the same thing
|
||||
|
||||
for async ones, they can be assigned without knowing whether or not they succeeded (`create`)

||||

if you issue a create, and it technically could go to any number of hosts, but only one host responds, it will succeed
|
||||
but if you issue a create and somehow 2 hosts both think they own that task, it will fail and throw a big error. cuz it expects exactly 1 to own the create task
|
||||
|
||||
currently its not set up to do any polling. its not really like a queue at all. It's all immediate for the most part
