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

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

Install the CData JDBC Driver for Recurly

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

Start a Spark Shell and Connect to Recurly Data

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

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

2. With the shell running, you can connect to Recurly 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 Recurly Profile on disk (e.g. C:\profiles\Recurly.apip). Next, set the ProfileSettings connection property to the connection string for Recurly (see below).

   Recurly API Profile Settings

   Navigate to Integrations > API Credentials in your Recurly account and click Add Private API Key.

   Built-in Connection String Designer

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

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

   scala> api_df.registerTable("accountacquisition")

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

   scala> api_df.sqlContext.sql("SELECT Id, Object FROM AccountAcquisition WHERE Channel = organic").collect.foreach(println)

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