How to work with ShipEngine 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 ShipEngine, Spark can work with live ShipEngine data. This article describes how to connect to and query ShipEngine data from a Spark shell.
The CData JDBC Driver offers unmatched performance for interacting with live ShipEngine data due to optimized data processing built into the driver. When you issue complex SQL queries to ShipEngine, the driver pushes supported SQL operations, like filters and aggregations, directly to ShipEngine 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 ShipEngine data using native data types.
Install the CData JDBC Driver for ShipEngine
Download the CData JDBC Driver for ShipEngine installer, unzip the package, and run the JAR file to install the driver.
Start a Spark Shell and Connect to ShipEngine Data
- Open a terminal and start the Spark shell with the CData JDBC Driver for ShipEngine JAR file as the jars parameter:
$ spark-shell --jars /CData/CData JDBC Driver for ShipEngine/lib/cdata.jdbc.api.jar
- With the shell running, you can connect to ShipEngine 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 ShipEngine Profile on disk (e.g. C:\profiles\ShipEngine.apip). Next, set the ProfileSettings connection property to the connection string for ShipEngine (see below).
ShipEngine API Profile Settings
Retrieve your ShipEngine API Key from the Dashboard at app.shipengine.com under API Management.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the ShipEngine 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 ShipEngine, using the connection string generated above.
scala> val api_df = spark.sqlContext.read.format("jdbc").option("url", "jdbc:api:Profile=C:\profiles\ShipEngine.apip;ProfileSettings='APIKey=your_api_key';").option("dbtable","BatchErrors").option("driver","cdata.jdbc.api.APIDriver").load() - Once you connect and the data is loaded you will see the table schema displayed.
Register the ShipEngine data as a temporary table:
scala> api_df.registerTable("batcherrors")-
Perform custom SQL queries against the Data using commands like the one below:
scala> api_df.sqlContext.sql("SELECT BatchId, Error FROM BatchErrors WHERE BatchId = batch_123").collect.foreach(println)You will see the results displayed in the console, similar to the following:
