title: Will multiple AJAX DB write calls to MySQL cause connection fails?
body: <p>I have a page on my site that lists residential units. For each of these units, you can then add a few values, and by clicking GO I loop through the rows and:</p>
  
  <p>1) Check if the values are correct
  2) Initiate an async call that writes the data to my DB.</p>
  
  <p>Now, when I loop through the calls its obvious that the all don't initiate simultaneously (I change the row color to indicate that it's processing, and they change one by one with a slight delay) since I'm looping through with Javascript.</p>
  
  <p>Should I limit the number of rows on the page? There can be a few hundred on each page as it is now, but I could easily limit it to X number of building floors with say 10-20 units per floor?</p>
  
  <p>I'm worried that the DB will be overloaded. How many connections can the DB handle? What do you guys think/recommend?</p>
