The Playlist tutorialAn introduction to web application development using DataStax Enterprise and Apache Cassandra.
Setting up your environmentConfigure your environment to begin assembling the Playlist example application.
Architecture of the Playlist example applicationThe Playlist example application is a Java web application that manages a music library.
Step 1: Connecting to Cassandra from a web applicationThe simplest version of Playlist shows how to connect to Cassandra and display information from the system table.
Step 2: Adding artist and track featuresEnhance the Playlist application by adding the ability to search the song catalog by track and artist name, with corresponding tables and CQL queries.
Building and running step 2Create the database keyspace, create the artist and track tables, populate the tables, and then build and run the Playlist example application.
Step 3: Adding hot tracksYou can alter existing tables to add new columns.
Building and running step 3Alter the tables to add a new boolean column, and modify the application to allow users to select starred tracks.
Step 4: Adding users and custom playlistsEnhance the Playlist application to store user playlists.
Building and running step 4Add new tables and modify the application code to allow users to log in and create music playlists that contain different music tracks.
Step 5: Add statistics views to monitor PlaylistEnhance the Playlist application by adding counters to collect statistics.
Building and running step 5Add a table to collect the statistics of the Playlist application, and modify Playlist to display the statistics to users.
Step 6: Optimize the Playlist applicationOptimize the Playlist application with paging result sets and caching.
Building and running step 6Row caches and query paging help improve the performance of Cassandra when running queries that return large result sets.
