Avro JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Avro.



Use the CData JDBC Driver for Avro in SnapLogic to integrate Avro with External Services.

SnapLogic is an integration platform-as-a-service (iPaaS) that allows users to create data integration flows with no code. When paired with the CData JDBC Drivers, users get access to live data from more than 250+ SaaS, Big Data and NoSQL sources, including Avro, in their SnapLogic workflows.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Avro data. When platforms issue complex SQL queries to Avro, the driver pushes supported SQL operations, like filters and aggregations, directly to Avro and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying lets you work with Avro data using native data types.

Connect to Avro in SnapLogic

To connect to Avro data in SnapLogic, download and install the CData Avro JDBC Driver. Follow the installation dialog. When the installation is complete, the JAR file can be found in the installation directory (C:/Program Files/CData/CData JDBC Driver for Avro/lib by default).

Upload the Avro JDBC Driver

After installation, upload the JDBC JAR file to a location in SnapLogic (for example, projects/Jerod Johnson) from the Manager tab.

Configure the Connection

Once the JDBC Driver is uploaded, we can create the connection to Avro.

  1. Navigate to the Designer tab
  2. Expand "JDBC" from Snaps and drag a "Generic JDBC - Select" snap onto the designer
  3. Click Add Account (or select an existing one) and click "Continue"
  4. In the next form, configure the JDBC connection properties:
    • Under JDBC JARs, add the JAR file we previously uploaded
    • Set JDBC Driver Class to cdata.jdbc.avro.AvroDriver
    • Set JDBC URL to a JDBC connection string for the Avro JDBC Driver, for example: jdbc:avro:URI=C:/folder/table.avroRTK=XXXXXX;InitiateOAuth=GETANDREFRESH

      NOTE: RTK is a trial or full key. Contact our Support team for more information.

      Built-In Connection String Designer

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

      java -jar cdata.jdbc.avro.jar

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

      Connect to your local Avro file(s) by setting the URI connection property to the location of the Avro file.
  5. After entering the connection properties, click "Validate" and "Apply"

Read Avro Data

In the form that opens after validating and applying the connection, configure your query.

  • Set Schema name to "Avro"
  • Set Table name to a table for Avro using the schema name, for example: "Avro"."SampleTable_1" (use the drop-down to see the full list of available tables)
  • Add Output fields for each item you wish to work with from the table

Save the Generic JDBC - Select snap.

With connection and query configured, click the end of the snap to preview the data (highlighted below).

Once you confirm the results are what you expect, you can add additional snaps to funnel your Avro data to another endpoint.

Piping Avro Data to External Services

For this article, we will load data in a Google Spreadsheet. You can use any of the supported snaps, or even use a Generic JDBC snap with another CData JDBC Driver, to move data into an external service.

  1. Start by dropping a "Worksheet Writer" snap onto the end of the "Generic JDBC - Select" snap.
  2. Add an account to connect to Google Sheets
  3. Configure the Worksheet Writer snap to write your Avro data to a Google Spreadsheet

You can now execute the fully configured pipeline to extract data from Avro and push it into a Google Spreadsheet.
