title: MySQL Group Replication or a Single Server is enough?
body: <p>I'm planning to create a system which tracks visitors clicks into the database. I'm expecting around 1M inserts/day into the Database.</p>
  
  <p>On the backend, I'll have an analytics system which will analyze all the data that's been collected over the days/weeks/months/years.</p>
  
  <p>My question is: is it a practical approach to have 2 different MySQL Servers + 1 Web server? MySQL Server A would insert the clicks into it's DB and it would be connected to MySQL Server B by group replication, so whenever I create reports, etc on MySQL Server B, it doesn't load Server A heavily.</p>
  
  <p>These 2 Database servers would then be connected to the Web Server which would handle all the click requests and displaying the backend reports also.</p>
  
  <p>Is it a practical solution, or is it better to have one bigger server to handle all the MySQL data? Or have multiple MySQL servers that are load balancing each other? Anything else perhaps?</p>
