cassandra-trainings

Summary

Application Stub for the Cassandra Workshop. This is a simple Cassandra and Play Framework web application "HeapOverflow", which was inspired by http://stackoverflow.com.

HeapOverflow enables:

• register and manage your account
• ask any question
• rank questions
• answer questions
• vote questions
• comment questions and answers

Question ranks are the key feature of the application:

• Recent - ordered descending by creation date
• Popular - ordered descending by number of votes
• Active - ordered descending by last modification date (time of last comment, answer etc.)
• Unanswered - list of recent questions without any answer
• Asked - list of questions created by the logged-in user, ordered descending by creation date
• Followed - list of questions followed-by the logged-in user, ordered descending by creation date

• /app/dao/ - Cassandra DAOs
• /app/model/ - Cassandra model

The application contains three examples of different approach of data access:

• DataStax driver PreparedStatement - dao.UserDAO
• DataStax mapper - dao.QuestionDAO
• Spring Data Cassandra - dao.spring.ActiveQuestionsDAO

You can use the method which you prefere.
