Example of a bit of the java api used for cassandra access

cassandra-quick-example

Demo of some data access of cassandra with some datastax libraries.

Do the following to get Cassandra working on your machine:

• Download Cassandra and install
• Start up Cassandra: "cassandra -f" will start it up in the foreground so you don't forget about it
• Add the datastax dependencies to your project
• In order to create a table you can use, you first need to create a keyspace
• Then you can create you table and insert data into it; running this script will create the keyspace, table, and load the data
• To run the script included in this project, run the following command: "cqlsh -f person-create.cql"

The java program has examples of

• Usage of a mapper for querying individual records and collections using the Person model The annotations on Person are
  • @Table
  • @Column (required if the column name in the db is different then the name of the field on the Model)
  • @PartitionKey
• Doing an Insert with a mapper
• Using a QueryBuilder and ResultSet

I just put this together so I would have some notes to remember a video I just watched on Safari Books Online: Mastering Cassandra Essentials.
