Please try to design documents structure and provide partition key for the following cases:

  1. Student’s registration book
  2. Blog post with comments – remember about all attributes
  3. Plant monitor IoT device (soil moisture, soil fertility, light intensity, air temperature)
  4. Auction house catalogue
  5. Event registration (like g. MeetUp)
  6. Provide your example – only one

Please remember that:

  • There is no one single answer on those issues.
  • You should always adjust it to business case of your solution.
  • You are working with noSQL database and you have more options for shaping data
