Load LinkedIn Data to a Database Using Embulk

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

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

Configure a JDBC Connection to LinkedIn 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 LinkedIn\lib).

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

LinkedIn uses the OAuth 2 authentication standard. Obtain the OAuthClientId and OAuthClientSecret by registering an app with LinkedIn. For more information refer to our authentication guide.

Built-in Connection String Designer

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

java -jar cdata.jdbc.linkedin.jar

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

Below is a typical JDBC connection string for LinkedIn:

jdbc:linkedin:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX;InitiateOAuth=GETANDREFRESH;

Load LinkedIn 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 LinkedIn data into MySQL using Embulk.

Create a Job to Load LinkedIn Data

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

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

Sample Config File (linkedin-mysql.yml)

in:
	type: jdbc
	driver_path: C:\Program Files\CData[product_name] 20xx\lib\cdata.jdbc.linkedin.jar
	driver_class: cdata.jdbc.linkedin.LinkedInDriver
	url: jdbc:linkedin:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX;InitiateOAuth=GETANDREFRESH;
	table: "CompanyStatusUpdates"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "CompanyStatusUpdates"
	mode: insert

After creating the file, run the Embulk job.

embulk run linkedin-mysql.yml

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

Load Filtered LinkedIn 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.linkedin.jar
	driver_class: cdata.jdbc.linkedin.LinkedInDriver
	url: jdbc:linkedin:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXX;InitiateOAuth=GETANDREFRESH;
	query: "SELECT VisibilityCode, Comment FROM CompanyStatusUpdates WHERE [RecordId] = 1"
out: 
	type: mysql
	host: localhost
	database: DatabaseName
	user: UserId
	password: UserPassword
	table: "CompanyStatusUpdates"
	mode: insert
