Load WordPress Data to a Database Using Embulk

Embulk is an open source bulk data loader. When paired with the CData JDBC Driver for Wordpress, Embulk easily loads data from WordPress to any supported destination. In this article, we explain how to use the CData JDBC Driver for Wordpress in Embulk to load WordPress data to a MySQL dtabase.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live WordPress data. When you issue complex SQL queries to WordPress, the driver pushes supported SQL operations, like filters and aggregations, directly to WordPress and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Configure a JDBC Connection to WordPress Data

Before creating a bulk load job in Embulk, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Wordpress\lib).

Embulk supports JDBC connectivity, so you can easily connect to WordPress and execute SQL queries. Before creating a bulk load job, create a JDBC URL for authenticating with WordPress.

To connect to WordPress, set the URL property and other authentication properties. WordPress supports Basic (User and Password) and OAuth2.0 authentication, though Basic is recommended for a testing environment only. To connect with OAuth register an app with WordPress.

See the Getting Started guide in the CData driver documentation for more information.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the WordPress JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.wordpress.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for WordPress:

jdbc:wordpress:Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH;

Load WordPress Data in Embulk

After installing the CData JDBC Driver and creating a JDBC connection string, install the required Embulk plugins.

Install Embulk Input & Output Plugins

1. Install the JDBC Input Plugin in Embulk.
   https://github.com/embulk/embulk-input-jdbc/tree/master/embulk-input-jdbc

embulk gem install embulk-input-jdbc

2. In this article, we use MySQL as the destination database. You can also choose SQL Server, PostgreSQL, or Google BigQuery as the destination using the output Plugins.
   https://github.com/embulk/embulk-output-jdbc/tree/master/embulk-output-mysql

   embulk gem install embulk-output-mysql
   

With the input and output plugins installed, we are ready to load WordPress data into MySQL using Embulk.

Create a Job to Load WordPress Data

Start by creating a config file in Embulk, using a name like wordpress-mysql.yml.

1. For the input plugin options, use the CData JDBC Driver for Wordpress, including the path to the driver JAR file, the driver class (e.g. cdata.jdbc.wordpress.WordPressDriver), and the JDBC URL from above
2. For the output plugin options, use the values and credentials for the MySQL database

Sample Config File (wordpress-mysql.yml)

in:
	type: jdbc
	driver_path: C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.wordpress.jar
	driver_class: cdata.jdbc.wordpress.WordPressDriver
	url: jdbc:wordpress:Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH;
	table: "Categories"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "Categories"
	mode: insert

After creating the file, run the Embulk job.

embulk run wordpress-mysql.yml

After running the the Embulk job, find the Salesforce data in the MySQL table.

Load Filtered WordPress Data

In addition to loading data directly from a table, you can use a custom SQL query to have more granular control of the data loaded. You can also perform increment loads by setting a last updated column in a SQL WHERE clause in the query field.

in:
	type: jdbc
	driver_path: C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.wordpress.jar
	driver_class: cdata.jdbc.wordpress.WordPressDriver
	url: jdbc:wordpress:Url=http://www.yourwordpresshost.com;InitiateOAuth=GETANDREFRESH;
	query: "SELECT Id, Name FROM Categories WHERE [RecordId] = 1"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "Categories"
	mode: insert
