Scanning a DynamoDB table

This example demonstrates how to scan and read data from a DynamoDB table using the DynamoDB Scan Snap.

Before you begin, ensure you have:

  • A configured DynamoDB Account .
  • An existing DynamoDB table with data to scan.
  • Appropriate read permissions on the DynamoDB table.

This pipeline demonstrates how to perform a scan operation on a DynamoDB table. The DynamoDB Scan Snap reads all items from the specified table and returns the data.

  1. Configure the DynamoDB Scan Snap.

    In the DynamoDB Scan Snap settings:

    • Account: Select your configured DynamoDB account.
    • Table name: Enter the name of the table you want to scan.
    • Projection expression: Specify the attributes to retrieve (optional). If not specified, all attributes are returned.
    • Filter expression: Add filtering criteria to return only items that match specific conditions (optional).
    • Segment: For parallel scans, specify the segment number (optional).
    • Total segments: For parallel scans, specify the total number of segments (optional).

  2. Validate and execute the pipeline.

    Click Validate to verify the pipeline configuration, then execute the pipeline to scan the table.

The DynamoDB Scan Snap reads data from the DynamoDB table and returns all items (or filtered items if a filter expression is specified). The output displays the retrieved records.
