the use case is, i have a request that requires several megabytes of data from a postgresql database. i cache as much as i can in the worker memory, but for a fresh worker, i have to get all that data out of postgres.
i have 1 query that tells me all the keys that have new data (something like last updated timestamp), and then another query that gets the new data for all the keys that have seen updates.
my postgres database started getting bandwidth throttled (blue line) because of the workers fetching so much data from it. so i started storing the data for each key + last updated in kv and fetch from kv first
