      For the inline chain the profiling-stackframes index needs '_source' to be enabled.
      Also, doc_values for the fields below are disabled to not store the values twice.
      Using synthetic source reduces storage size by ~50% but requires "concatenation"
      of arrays and adds latency when _source is reconstructed at query time.
      This last point is why we don't want to use synthetic source right now.
