1. What is Over-fetching?

Junior
  1. A.the downside that POSTing to one URL forgoes REST's per-URL response caching, pushing caching into the client or layer
  2. B.when one endpoint returns too little, forcing extra round-trips that a single nested selection can collapse
  3. C.the property that every field, argument and result is described by an enforced, introspectable schema contract
  4. D.retrieving more fields than the client needs, a waste that a precise per-field selection avoids
