Deploying new instances of apollo-router almost inevitably ends up with a spike in timeouts. Initially thinking this was due to large query plans / done in JS (related), it is instead mostly due to the synchronous nature of the planner, with a ton of queuing happening for new instances receiving a high cardinality of new queries to plan.
There is a ton of gotchas with using a pool of planners. Errors especially are hard to recover from. I'm going to use this branch to test things out and see what kinds of improvements could be achieved.
