How to work with ZeroBounce 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 ZeroBounce, Spark can work with live ZeroBounce data. This article describes how to connect to and query ZeroBounce data from a Spark shell.

The CData JDBC Driver offers unmatched performance for interacting with live ZeroBounce data due to optimized data processing built into the driver. When you issue complex SQL queries to ZeroBounce, the driver pushes supported SQL operations, like filters and aggregations, directly to ZeroBounce 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 ZeroBounce data using native data types.

Install the CData JDBC Driver for ZeroBounce

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

Start a Spark Shell and Connect to ZeroBounce Data

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

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

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

   Using API Key Authentication

   ZeroBounce uses API key authentication. To obtain an API key:

   1. Log in to your ZeroBounce account at https://app.zerobounce.net
   2. Navigate to the API tab in your account dashboard
   3. Copy the API key displayed on the page

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your ZeroBounce API key.

   Example Connection String

   Profile=C:\profiles\ZeroBounce.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";
   

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the ZeroBounce 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 ZeroBounce, using the connection string generated above.

   scala> val api_df = spark.sqlContext.read.format("jdbc").option("url", "jdbc:api:Profile=C:\profiles\ZeroBounce.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";").option("dbtable","Credits").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 ZeroBounce data as a temporary table:

   scala> api_df.registerTable("credits")

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

   scala> api_df.sqlContext.sql("SELECT ,  FROM Credits WHERE  = ").collect.foreach(println)

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