@dan_abramov For best results, make sure to line up the transients properly and perhaps use the camelot wheel to check if tunes play well together harmonically.
@Popeska@elonmusk@sampullara Only way to know for sure is to profile. I would however find it hard to believe all downstream services are being hit for a timeline query, as only the resolvers that are necessary to fulfill the request are fired. N+1 problem is also easily solved with req dedupe/memoization.
