How to work with Helpscout 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 Helpscout, Spark can work with live Helpscout data. This article describes how to connect to and query Helpscout data from a Spark shell.
The CData JDBC Driver offers unmatched performance for interacting with live Helpscout data due to optimized data processing built into the driver. When you issue complex SQL queries to Helpscout, the driver pushes supported SQL operations, like filters and aggregations, directly to Helpscout 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 Helpscout data using native data types.
Install the CData JDBC Driver for Helpscout
Download the CData JDBC Driver for Helpscout installer, unzip the package, and run the JAR file to install the driver.
Start a Spark Shell and Connect to Helpscout Data
- Open a terminal and start the Spark shell with the CData JDBC Driver for Helpscout JAR file as the jars parameter:
$ spark-shell --jars /CData/CData JDBC Driver for Helpscout/lib/cdata.jdbc.api.jar
- With the shell running, you can connect to Helpscout 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 Helpscout Profile on disk (e.g. C:\profiles\Helpscout.apip). Next, set the ProfileSettings connection property to the connection string for Helpscout (see below).
Helpscout API Profile Settings
Generate an API key in Help Scout by going to Your Profile > Authentication > Generate an API Key.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Helpscout 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 Helpscout, using the connection string generated above.
scala> val api_df = spark.sqlContext.read.format("jdbc").option("url", "jdbc:api:Profile=C:\profiles\Helpscout.apip;ProfileSettings='APIKey=your_api_key';").option("dbtable","Categories").option("driver","cdata.jdbc.api.APIDriver").load() - Once you connect and the data is loaded you will see the table schema displayed.
Register the Helpscout data as a temporary table:
scala> api_df.registerTable("categories")-
Perform custom SQL queries against the Data using commands like the one below:
scala> api_df.sqlContext.sql("SELECT Id, Number FROM Categories WHERE Visibility = public").collect.foreach(println)You will see the results displayed in the console, similar to the following:
