Project includes three examples of how to access a Cassandra data store using Java.

The model for the data we want to store is based on a set of atmospheric sensors that collect time series data collected on a reasonably quick interval (minutes). The fields of the modeled entity have been chosen to demonstrate how to store heterogeneous data types (most examples just use strings, boring).

A set of slides and a video presentation will be forthcoming for this project. This README will be updated with links.

Example 1: Accessing a datastore that uses Cassandra super columns to store the various fields of the entity using the Hector library.

Example 2: Accessing a datastore that uses normal Cassandra columns, packing the entity in a protocol buffer using the Hector library.

Example 3: Accessing a datastore that uses normal Cassandra columns, packing the entity in a protocol buffer using the Astyanax library and asynchronous API.

To run this example (assumes you have Maven 3 installed):

Clone the repo on your local machine
At the top level of the project, run:

> mvn clean install

All tests should pass. Review tests to see how to use the examples.

A PDF version of the slides for the presentation that goes with this code can be found in the slides directory. In addition, the slides can be viewed at http://www.slideshare.net/jmctee/cassandra-clienttutorial.

Note: To run these examples, you do no need to install Cassandra, as the tests use embedded Cassandra. The preso will cover how to use these examples with a non-embedded Cassandra instance.

More to come, hope this is helpful...
