title: NiFi: Storing file contents in memory or global variables
body: <p>I have some <code>key value pairs</code> in a text file <code>(sftp server)</code> and would like those values to be stored
  somewhere in <code>memory</code> or as <code>global variables</code> so that I can use it in all my <code>ExecuteScript</code> processors.
  I have like more than 20 <code>ExecuteScript</code> routed based on different types of data and I need to use these <code>key value pairs</code>
  inside these processors. 
  I cannot store these values as NiFi global variables since the file content is not the same for each run of my NiFi Data flow.</p>
  
  <p>The way Im expecting is when my NiFi flow starts these file contents has to stored <code>somewhere(memory/variables)</code> so I can refer it in all my scripts.</p>
  
  <p>Can this be done?
  Any suggestions or recommendations for this would be much appreciated.</p>
