title: How to implement HTTP request queue in Java
body: <p>we are trying to setup Architecture for Application.This is first time for us.This Application is not interact with End-Users,it's for my internal computations purpose.
  We have a remote <code>DBServer</code>(Ms sql server azure) with 1 database name as <code>DBTesting</code>. Whenever any data was modified in <code>DBTesting</code>,it triggers java Application name as <code>App1</code> .</p>
  
  <p>Question 1:</p>
  
  <p>What are the possibilities to trigger <code>App1</code> .</p>
  
  <p>In <code>App1</code>, I am running <code>.exe</code> file,which is written in <code>C</code> language.It takes 20 min for evaluation. If <code>DBTesting</code> is modified many times with in 20 min, it sends that many number of requests from <code>DBTesting</code> to <code>App1</code>.But I don't want to handle more number of requests at a time.So I want to trigger <code>App1</code> in queue  base. Once previous <code>Http</code> request is done then only Queue will be release next HTTP request.</p>
  
  <p>Question 2:</p>
  
  <p>Is there any way to Implement this using <code>Java</code> or any other technologies</p>
  
  <p>we are interacting Database with this <a href="https://coxy7ezff6.database.windows.net/" rel="nofollow">Link</a></p>
