I need a Top Ten Scores functionality implemented for Cassandra database using Spark with a spark cassandra connector. The Idea is simple: 1. we have a table of game events in Cassandra, with gameId, userId, timestamp and score; 2. we need a Spark job running periodically to calculate and populate the Top Ten Scores table in Cassandra: CREATE TABLE TopTen ( gameId uuid, process_timestamp timestamp, total_score double, userId uuid, PRIMARY KEY(gameId, process_timestamp, score) ) WITH CLUSTERING ORDER BY(process_timestamp DESC, total_score DESC); After populating it, we select first ten rows for each game to have the top ten scores. You need to implement the java program for it.
