Dependencies

  • HTTP exchange clients: AuthInternalClient, SocialInternalClient, SocialFriendshipInternalClient, SocialEmojiInternalClient, MessagingInternalClient, NotificationInternalClient.
  • Photon geocoding (PhotonClient).
  • Redis user-profile cache and album search rate limit.

Timeouts and circuit breakers belong on the client adapter, not in the use case. A failed downstream call for a non-critical side effect should become an outbox or inbox retry, not a user-facing 500, when the business write has already committed.
