cf scale command sequence
|
Siva Balan <mailsiva@...>
When I issue a cf scale command to bring down the number of app instances
from, say 10 to 5, what is the sequence of events that take place to make this happen? I am particularly interested to know if the containers are removed before their routes are removed from the gorouter or is it the other way round? This question if for both diego and DEA versions.

It is pretty much a race. It can happen either way. GoRouter will retry

on failed connects so if the route remains when the container is removed, the next instance will be tried. - Michael

Thanks. What I am concerned about are the inflight transactions on the

container when it is being destroyed. What happens to them? If the routes are removed from the GoRouter before the container is destroyed, I believe, it has some lead time to process inflight transactions. But if the route is removed after the container is destroyed, the probability of inflight transactions getting killed is more. Also, I dont understand how it can happen either way. The code path should do one or the other but not both.
