Use CData driver technologies to create a virtual data source for MySQL data in the Denodo Virtual DataPort Administrator.
Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for MySQL, Denodo users can work with live MySQL data alongside other enterprise data sources. This article walks through creating a virtual data source for MySQL in the Denodo Virtual DataPort Administrator.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live MySQL data. When you issue complex SQL queries to MySQL, the driver pushes supported SQL operations, like filters and aggregations, directly to MySQL and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze MySQL data using native data types.
Create the MySQL Virtual Port
To connect to live MySQL data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.
- Download the CData JDBC Driver for MySQL installer, unzip the package, and run the JAR file to install the driver.
- Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for MySQL\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-mysql-19).
- Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
- Right-click "admin" and select New -> Data source -> JDBC.
- Configure the JDBC Connection:
- Name: your choice, e.g.: mysql
- Database adapter: Generic
- Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-mysql-19
- Driver class: cdata.jdbc.mysql.MySQLDriver
Database URI: Set this to a JDBC URL using the necessary connection properties. For example,
jdbc:mysql:User=myUser;Password=myPassword;Database=NorthWind;Server=myServer;Port=3306;
Information on creating the Database URI follows:
Built-In Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the MySQL JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.mysql.jar
Fill in the connection properties and copy the connection string to the clipboard.
The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.
- Click the "Test connection" button to confirm the configuration and click Save.
View MySQL Data in the VirtualPort Administrator Tool
After creating the data source, you can create a base view of MySQL data for use in the Denodo Platform.
- Click the "Create base view" button in the newly created VirtualPort (admin.MySQL).
- Expand the object tree and select the objects (tables) you wish to import.
- Click the "Create selected" button to create views of the MySQL data.
Optional: Click "Create associations from foreign keys" to define relationships between the objects. - With the view(s) created, navigate to a table (cdata_mysql_orders) in the Server Explorer and double-click the selected table.
- In the new tab, click "Execution panel" to open a query panel.
- Customize the query in the "Execute" tab or use the default:
SELECT * FROM cdata_mysql_orders CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
- Click Execute to view the data.
With the base view created, you can now work with live MySQL data like you would any other data source in Denodo Platform, for example, querying MySQL in the Denodo Data Catalog.
