Validate Amazon DynamoDB Data with QuerySurge



Access and validate Amazon DynamoDB data in QuerySurge using the CData JDBC Driver.

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for Amazon DynamoDB, QuerySurge can work with live Amazon DynamoDB data. This article walks through connecting to Amazon DynamoDB data from QuerySurge.

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

Connecting to Amazon DynamoDB Data in QuerySurge

To connect to live Amazon DynamoDB data from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.

Deploy the JDBC Driver

  1. Download the CData JDBC Driver for Amazon DynamoDB installer, unzip the package, and run the JAR file to install the driver.
  2. Once the driver is installed, stop the Agent Service.
  3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Amazon DynamoDB\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
  4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to Amazon DynamoDB

  1. Log into QuerySurge and navigate to the Admin view.
  2. Click Configuration -> Connections in the Administration Tree.
  3. Click Add to create a new connection.
  4. In the QuerySurge Connection Wizard, click Next.
  5. Name the connection (e.g. CData JDBC Connection to Amazon DynamoDB).
  6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
  7. Set the Driver Class to cdata.jdbc.amazondynamodb.AmazonDynamoDBDriver and click Next.
  8. Set the Connection URL using the necessary connection properties to authenticate with Amazon DynamoDB. Your Connection URL will look something like the following:

    jdbc:amazondynamodb:Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.amazondynamodb.jar

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

    The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

  9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Lead LIMIT 1) and click Next.
  10. Click Test Connection to ensure the connection is configured properly and click Save to add the connection.

Once the connection is added, you can write SQL queries against your Amazon DynamoDB data in QuerySurge.

Compare Amazon DynamoDB Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying Amazon DynamoDB data with a QueryPair.

  1. Select "Design Library" from the Design Menu
  2. Click QueryPairs under QuerySurge Design
  3. Click "Create New QueryPair"
  4. Name the QueryPair and click Save
  5. In either the Source or Target panes, select the connection created above (select the same connection to query Amazon DynamoDB twice or another connection to perform a comparison)
  6. Write queries in the Editor for each pane, e.g. SELECT * FROM Lead
  7. Click the "Design-Time Run" tab to execute the queries
  8. When the query execution is finished, click "View Query Results" to see the Amazon DynamoDB data returned by the query
