Work with PayPal Data in Apache Spark Using SQL

Access and process PayPal Data in Apache Spark using the CData JDBC Driver.

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

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

Install the CData JDBC Driver for PayPal

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

Start a Spark Shell and Connect to PayPal Data

  1. Open a terminal and start the Spark shell with the CData JDBC Driver for PayPal JAR file as the jars parameter: $ spark-shell --jars /CData/CData JDBC Driver for PayPal/lib/cdata.jdbc.paypal.jar
  2. With the shell running, you can connect to PayPal with a JDBC URL and use the SQL Context load() function to read a table.

    The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

    • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
    • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

    See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

    To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

    For testing purposes you can set UseSandbox to true and use sandbox credentials.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.paypal.jar

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

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

    scala> val paypal_df = spark.sqlContext.read.format("jdbc").option("url", "jdbc:paypal:Schema=SOAP;Username=sandbox-facilitator_api1.test.com;Password=xyz123;Signature=zx2127;").option("dbtable","Transactions").option("driver","cdata.jdbc.paypal.PayPalDriver").load()
  3. Once you connect and the data is loaded you will see the table schema displayed.
  4. Register the PayPal data as a temporary table:

    scala> paypal_df.registerTable("transactions")
  5. Perform custom SQL queries against the Data using commands like the one below:

    scala> paypal_df.sqlContext.sql("SELECT Date, GrossAmount FROM Transactions WHERE TransactionClass = Received").collect.foreach(println)

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