      • Evaluate singletons which use repeated scheduled polling (janitor MB-47507)
      • Improve caching (fine grained invalidation)
      • Introduce fine grained streaming change subscriptions (MB-38523)
      • On change triggering, wake up a single process to evaluation diff and only notify subscribers if there is a diff
      • Communicates diff to subscribes such that they can reduce or eliminate a follow up queries.
      • Evaluate REST APIs and polling callers. Try to switch them to use streaming APIs.
      • Notice reductions captured here illustrating compute spent on polling requests, streaming notifications, and per memcachd bucket monitoring.
      • See dependent tickets associated
