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

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

Install the CData JDBC Driver for Pingdom

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

Start a Spark Shell and Connect to Pingdom Data

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

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

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

   Pingdom API Profile Settings

   In your Pingdom account, navigate to Integrations > The Pingdom API and create a new API Token to use as your API key.

   Built-in Connection String Designer

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

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

   scala> api_df.registerTable("actions")

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

   scala> api_df.sqlContext.sql("SELECT UserId, Username FROM Actions WHERE Status = delivered").collect.foreach(println)

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