AWS DynamoDB actions

This page provides a reference for AWS DynamoDB actions available in the workflow automation actions catalog. Use these actions to read, write, update, and delete items in DynamoDB tables, and to inspect or modify table configuration directly from a workflow definition.

Prerequisites

For prerequisites and credentials setup, see Set up AWS credentials.

All DynamoDB actions accept the same auth inputs. Use awsRoleArn (recommended) or the access key pair.

Scan a table

The action identifier is aws.dynamodb.scan.

Returns items from a DynamoDB table or index by scanning the entire table, with optional filtering. A single scan response is limited to 100 KB by Workflow Automation (DynamoDB's own limit is 1 MB). Use limit and exclusiveStartKey to paginate through large tables.

중요

Workflow Automation enforces a 100 KB output size limit per action. aws.dynamodb.scan throws an output size limit exceeded exception when the response exceeds this limit, even though it may be within DynamoDB's own 1 MB per-response cap. Use limit and exclusiveStartKey to paginate results and stay within this limit.

The following table describes the input fields for this action.

Input	Type	Description	Example

`indexName`	String	Optional. Name of a local or global secondary index to scan instead of the base table.	`my-gsi`
`filterExpression`	String	Optional. A condition applied after items are read. Filtered items are not returned but still consume read capacity.	`#s = :status`
`projectionExpression`	String	Optional. Comma-separated list of attributes to retrieve. If omitted, all attributes are returned.	`id, #n`
`expressionAttributeNames`	Map	Optional. Substitution tokens for attribute names in expressions.	`{"#s": "status"}`
`expressionAttributeValues`	Map	Optional. Substitution values for expressions in low-level AttributeValue format.	`{":status": {"S": "ACTIVE"}}`

`response`	Object	Contains `Items` (matched items) and `LastEvaluatedKey` (present when more pages exist). See the Scan API reference.
`errorMessage`	String	Error message on failure.

Example

name: scan-dynamodb-table
description: Scan for active orders in DynamoDB
steps:
  - name: scanActiveOrders
    type: action
    action: aws.dynamodb.scan
    version: '1'

중요

Workflow Automation enforces a 100 KB output size limit per action. aws.dynamodb.query throws an output size limit exceeded exception when the response exceeds this limit, even though it may be within DynamoDB's own 1 MB per-response cap.
