This is a simple Java-based command line application that shows how to use a clustered columnstore index to improve performance.
The application does the following:
- The application uses the Microsoft JDBC connector to connect to SQL Server.
- Then it runs a simple query to get and display the version information.
- Next it runs queries to create an 'Example' database and a Orders table.
- A query is then run to generate some demo data in the Orders table.
- The application then runs a query to sum up the Price column in the Orders table.
- The elapsed time to run the query is shown.
- Then a clustered columnstore index is created.
- Lastly, the same query is run to sum the Price column in the Orders table.
- The elapsed time is shown for the query after the clustered columnstore index is added.
- The performance improvement from adding the columnstore index is shown.
To run this application you need to have the following installed:
After making changes to the .java file, recompile with this command:
To run this application from the directory where the project is cloned:
java -cp .:/<location of JDBC driver jar> ColumnstoreDemo
java -cp .:/Users/travis/Projects/sqljdbc42.jar ColumnstoreDemo
