How to work with Zoho Books Data in Apache Spark using SQL

Access and process Zoho Books 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 Zoho Books, Spark can work with live Zoho Books data. This article describes how to connect to and query Zoho Books data from a Spark shell.

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

Install the CData JDBC Driver for Zoho Books

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

Start a Spark Shell and Connect to Zoho Books Data

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

    Zoho Books uses the OAuth authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Getting Started guide in the Help documentation for an authentication guide.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.zohobooks.jar

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

    Configure the connection to Zoho Books, using the connection string generated above.

    scala> val zohobooks_df ="jdbc").option("url", "jdbc:zohobooks:OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;").option("dbtable","INVOICES").option("driver","cdata.jdbc.zohobooks.ZohoBooksDriver").load()
  3. Once you connect and the data is loaded you will see the table schema displayed.
  4. Register the Zoho Books data as a temporary table:

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

    scala> zohobooks_df.sqlContext.sql("SELECT InvoiceId, InvoiceNumber FROM INVOICES WHERE CustomerName = NewTech Industries").collect.foreach(println)

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