https://partypeak.atlassian.net/browse/AP-

Description

• watchgod is now included in the standard package as specified here which is why the build currently breaks.
• With the new Uvicorn release a configurable reload delay has also been introduced as specified here. I've set this to 1s which may help against the high CPU load we're seeing from the hot reload function.

Dependencies

Are there any dependencies in relation to pull requests in other Apollo repositories? If so please provide links to these pull requests

Additional notes

Nope
