Room DAO: Flow<List<User>> vs suspend fun getUsers(): List<User>
This tests reactivity versus one-shot queries in Room and coroutines. Flow emits on every table change on Room's dispatcher, while suspend returns a single snapshot requiring manual refresh.
This tests reactive streams versus one-shot suspend queries in Room. Flow<List<User>> creates an observable query Room monitors; it emits a new list whenever the table changes and runs on the query dispatcher. suspend fun getUsers(): List<User> fetches a static snapshot never updating unless manually refreshed. Both run on Room's query dispatcher, but Flow stays active and must be collected in a lifecycle-aware coroutine scope.
