relays scale well. we’re dealing with small json blobs and read heavy workloads. this lends extremely will to caching and horizontal scaling.

the hard part is the clients. in a permissionless network, clients will be bad actors. for your client to work well it must use sane data access patterns.

concretely:

- get the client’s websocket connection mgmt in order

- get the client’s data access patterns in order. batch queries, cache locally, etc

- harden your relays with rate limiting for stomping out bad clients

- implement good caching for your clients needs
