Validate Amazon S3 Data with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for Amazon S3, QuerySurge can work with live Amazon S3 data. This article walks through connecting to Amazon S3 data from QuerySurge.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Amazon S3 data. When you issue complex SQL queries to Amazon S3, the driver pushes supported SQL operations, like filters and aggregations, directly to Amazon S3 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 S3 data using native data types.

Connecting to Amazon S3 Data in QuerySurge

To connect to live Amazon S3 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 S3 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 S3\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 S3

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 S3).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.amazons3.AmazonS3Driver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with Amazon S3. Your Connection URL will look something like the following:

   jdbc:amazons3:AccessKey=a123;SecretKey=s123;

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Amazon S3 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.amazons3.jar

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

   To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

   Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

   For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM ObjectsACL 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 S3 data in QuerySurge.

Compare Amazon S3 Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying Amazon S3 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 S3 twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM ObjectsACL
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 S3 data returned by the query
