implementation :"iteration"|"lookup"|"batchLookup"

The type of implementation for fetchByKeys and containsKeys methods. Possible values are:
  • "iteration": the implementation uses fetchFirst iteratively to find the result
  • "lookup": the implementation uses direct lookup to find the result one key at a time. This may not be efficient if multiple keys need to be fetched.
  • "batchLookup": the implementation uses direct lookup to find the result for all keys in a single batch. This is the most efficient implemenation.
