# RPCReturnsObservables

`@Target([AnnotationTarget.FUNCTION]) annotation class RPCReturnsObservables`

If an RPC is tagged with this annotation it may return one or more observables anywhere in its response graph. Calling such a method comes with consequences: it's slower, and consumes server side resources as observations will buffer up on the server until they're consumed by the client.
