title: Load a large JSON file using multi threading/
body: <p>I am trying to load a large 3 GB JSON file. Currently, with JQ utility I can load the entire file in nearly 40 mins. Now, I want to know how I can use parallelism/multi threading approach in JQ in order to complete the process in less amount of time. I am using v1.5</p>
  
  <p><strong>Command Used:</strong></p>
  
  <pre><code>JQ.exe -r -s "map(.\"results\" | map({\"ID\": (((.\"body\"?.\"party\"?.\"xrefs\"?.\"xref\"//[] | map(select(ID))[]?.\"id\"?))//null), \"Name\": (((.\"body\"?.\"party\"?.\"general-info\"?.\"full-name\"?))//null)} | [(.\"ID\"//\"\"|tostring), (.\"Name\"//\"\"|tostring)])) | add[] | join(\"~\")" "\C:\InputFile.txt" &gt;"\C:\OutputFile.txt"
  </code></pre>
