I implemented a Prometheus Histogram to calculate response time and tried to send 10 concurrent requests.

Here does one request close the timer opened by another request in Prometheus. request 1 enters at t1 reqest2 enters at t2 request1 finishes at t3 But request1 close the counter started by requests measuring the response time as t3-t2 when it is actually t3-t1

Is this handled by Prometheus Instrumentation Library ? I use Java for instrumentation.
