search - Slot management and discovery with a twist -


i trying build discovery flow company , stuck @ 1 place. company's sellable entity doctor's appointment slots.

each slot has following attributes

  • starttime
  • endtime
  • doctorid

each doctor has following attributes

  • doctorid
  • doctor's location (latitude, longitude)

also each doctor has table ratings/reviews

now when searches, user should land on page should have following characteristics -

  • list of doctors
  • ability sort doctors ratings/location
  • ability apply filter particular time range slot

however since sorting applied on different entity (doctors) , filtering applied on different entity (slots), not able figure out how this.

i tried following approaches -

  • denormalize schema , associate rating , location each slot. solution not scalable. once slot created, further changes in location/rating not reflect.
  • make doctor primary entity , store related slots in 1 big json document , use elastic-search/mongodb queries. solution seems non scalable since number of slots keep on increasing every day, thereby increasing document size indefinitly

please help
