title: How i can integrate Apache Spark with the Play Framework to display predictions in real time?
body: <p>I'm doing some testing with Apache Spark, for my final project in college. I have a data set that I use to generate a decision tree, and make some predictions on new data.</p>
  
  <p>In the future, I think to use this project into production, where I would generate a decision tree (batch processing), and through a web interface or a mobile application receives new data, making the prediction of the class of that entry, and inform the result instantly to the user. And also go storing these new entries for after a while generating a new decision tree (batch processing), and repeat this process continuously.</p>
  
  <p>Despite the Apache Spark have the purpose of performing batch processing, there is the streaming API that allows you to receive real-time data, and in my application this data will only be used by a model built in a batch process with a decision tree, and how the prediction is quite fast, it allows the user to have the answer quickly.</p>
  
  <p>My question is what are the best ways to integrate Apache Spark with a web application (plan to use the Play Framework scala version)?</p>
