title: Parsing a running log
body: <p>I need to parse a running log. The log usually contains about 1.2-1.3 million lines a day. </p>
  
  <p>What is the best approach for parsing the log real time? I will be using Java for this implementation. Can anyone please suggest a method to read the log in real time as more and more entries are being added to the log?</p>
  
  <p>Any help would be duly appreciated. Thanks!</p>
