How to work with ZohoMarketingHub Data in Apache Spark using SQL

Apache Spark is a fast and general engine for large-scale data processing. When paired with the CData JDBC Driver for ZohoMarketingHub, Spark can work with live ZohoMarketingHub data. This article describes how to connect to and query ZohoMarketingHub data from a Spark shell.

The CData JDBC Driver offers unmatched performance for interacting with live ZohoMarketingHub data due to optimized data processing built into the driver. When you issue complex SQL queries to ZohoMarketingHub, the driver pushes supported SQL operations, like filters and aggregations, directly to ZohoMarketingHub and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can work with and analyze ZohoMarketingHub data using native data types.

Install the CData JDBC Driver for ZohoMarketingHub

Download the CData JDBC Driver for ZohoMarketingHub installer, unzip the package, and run the JAR file to install the driver.

Start a Spark Shell and Connect to ZohoMarketingHub Data

1. Open a terminal and start the Spark shell with the CData JDBC Driver for ZohoMarketingHub JAR file as the jars parameter:

   $ spark-shell --jars /CData/CData JDBC Driver for ZohoMarketingHub/lib/cdata.jdbc.api.jar
   

2. With the shell running, you can connect to ZohoMarketingHub with a JDBC URL and use the SQL Context load() function to read a table.

   Start by setting the Profile connection property to the location of the ZohoMarketingHub Profile on disk (e.g. C:\profiles\ZohoMarketingHub.apip). Next, set the ProfileSettings connection property to the connection string for ZohoMarketingHub (see below).

   Register an OAuth application in the Zoho Developer Console as a server-based application to obtain your Client ID and Client Secret.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.jar
   

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

   Configure the connection to ZohoMarketingHub, using the connection string generated above.

   scala> val api_df = spark.sqlContext.read.format("jdbc").option("url", "jdbc:api:Profile=C:\profiles\ZohoMarketingHub.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;").option("dbtable","CampaignDetails").option("driver","cdata.jdbc.api.APIDriver").load()
   

3. Once you connect and the data is loaded you will see the table schema displayed.

4. Register the ZohoMarketingHub data as a temporary table:

   scala> api_df.registerTable("campaigndetails")

5. Perform custom SQL queries against the Data using commands like the one below:

   scala> api_df.sqlContext.sql("SELECT CampaignKey, CampaignName FROM CampaignDetails WHERE CampaignName = Q4_Sales_Campaign").collect.foreach(println)

   You will see the results displayed in the console, similar to the following:
