I read that pageservers are shared between users. What if the memory capacity of the pageserver becomes the bottleneck? eg: some users perform full table scans and make most page access fallbacks to s3. Sorry for one more dumb question.

The answer is more pageservers. Right now we have 1 to may relationships 1 page server many tenants. But one tenant one pageserver. We will shard pageservers and make it many to many. The good news is that pageserver workload is constant space so it's relatively easy to schedule. Unlike query processing workloads that have joins and those are not constant memory space.
