      10.15.9 The end_markers_in_json System Variable
     </h3>

  <p>
   When reading a very large JSON document, it can be difficult to
      pair its closing bracket and opening brackets; setting
   <code class="literal">
    end_markers_in_json=ON
   </code>
   repeats the
      structure's key, if it has one, near the closing bracket.
      This variable affects both optimizer traces and the output of
   <code class="literal">
    EXPLAIN FORMAT=JSON
   </code>
   .

  <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">

    Note
   </div>
   <p>
    If
    <code class="literal">
     end_markers_in_json
    </code>
    is enabled, the
        repetition of the key means the result is not a valid JSON
        document, and causes JSON parsers to throw an error.
