title: Data retrieval and Join operations with cluster db server
body: <p>If any database spreads across multiple servers (ex. Microsoft Sql Server), how can we do join or filter operations. In my scenario, if suppose:</p>
  
  <ol>
  <li>A single table spreads across multiple servers how can we filter rows based on user input?</li>
  <li>If master table is there on one db server and transaction table is at another db server, how can we do join operations?</li>
  </ol>
  
  <p>Please let me know how can we achieve this and where can I get more details about this?</p>
