But i also want to update few fields of response so i am updating the response like<br> response.Hits.Hits[0].Source["current_time"] = utils.GetCurrentTimeInMillis()</p> <p>It is throwing error:concurrent read and write. It can be handled with mutex lock but the number of requests will be approx, 200K per minute and because of this i am getting high api latency.<br> How can i handle it, can someone help?</p>
