DataStax XML Demo

This application demonstrates how to store searchable XML documents in DataStax Enterprise.

Disclaimer: this is merely an educational demonstration. It is not intended for production. For brevity and clarity I have made no attempt at security; I have not defended against bad inputs; I have not profiled and optimized. In other words, please see the LICENSE and use at your own risk.

On the other hand, I hope this will show one way to store, index, and search XML documents in DataStax Enterprise. Check out the Technical Notes wiki page for a discussion on the design and implementation choices. Please write me with your thoughts and questions.

Configure the Cluster

Please see the Prepare the Cluster wiki for information on setting up a DataStax Enterprise cluster. A note on DSE versions: I originally developed and tested this project against DataStax Enterprise 4.8.4. I have updated it for DataStax Enterprise 4.8.10. It may also run well on other versions.

Contact Points

To specify contact points, use the contactPoints command line parameter. The value may contact multiple IPs in the format IP,IP,IP, without spaces. For example: -DcontactPoints=192.168.25.100,192.168.25.101.

Schema

To create the schema, run:

mvn clean compile exec:java -Dexec.mainClass=com.datastax.demo.schema.SchemaSetup -DcontactPoints=localhost

To remove the schema, run:

mvn clean compile exec:java -Dexec.mainClass=com.datastax.demo.schema.SchemaTeardown -DcontactPoints=localhost

Solr Core

To create the Solr core, run:

dsetool create_core datastax_xml_demo.movies schema=solr/movies_schema.xml solrconfig=solr/movies_solrconfig.xml

Populate Sample Data

Thank you to the Department of Computer Sciences at the University of Wisconsin-Madison for the XML movie data.

Bulk Load

To bulk load the database with sample data, run:

mvn clean compile exec:java -Dexec.mainClass="com.datastax.demo.xml.sampledata.BulkDataLoader" -DcontactPoints=localhost

Web Service & Streaming Updates
