I'd like to create something like a stored procedure - data in one type gets updated / added, this kicks off a job that does a couple queries, averages out a value, updates the field in another type. Is a server side subscription what i want here? And if it is, is there a guide/tutorial to walk me through it because i'm an idiot? 😄

yes, a SSS is what you want here 😛

ah, so you create the trigger and then write javascript to make your updates, and use graphql-request to do any further queries / mutations ?

indeed
