#hyperdrive better suited for this. tho 300-400ms for kv seems long

Hyperdrive is a good fit indeed @Alex Izydorczyk . But both Hyperdrive and Workers KV use the same caching layer. The difference is that Workers KV is persistent storage. If you write something to KV and access after it has been removed from cache (based on the cacheTtl parameter), you will be getting the value from KV's central stores https://developers.cloudflare.com/kv/concepts/how-kv-works/

Not to throw my own engineer under the bus, but he says " Hyperdrive is just a connection pooler with a very light caching layer. It makes connecting to postgres quick yes, but not a true caching layer like KV." -- it sounds like we have some fundamental misunderstanding of the product difference?

Does the webrtc of CALL have to follow the SFU protocol? Data to CloudFlare servers, does everyone's connection consume data?
