Defined in: src/constructs/idempotency-table/idempotency-table.ts:62

A DynamoDB table construct optimized for AWS Lambda Powertools idempotency functionality.

This construct creates a DynamoDB table with sensible defaults for idempotency use cases while enforcing specific requirements needed by the AWS Lambda Powertools library:

  • Partition key is always 'id' (STRING type)
  • TTL attribute is always 'expiration'
  • No sort key is allowed (simple primary key only)

All other DynamoDB table properties can be customized as needed.

Example​

// Basic usage with defaults
const idempotencyTable = new IdempotencyTable(this, 'IdempotencyTable', {
  tableName: 'my-function-idempotency'
});

// Custom configuration
const customTable = new IdempotencyTable(this, 'CustomTable', {
  tableName: 'custom-idempotency-table',
  removalPolicy: RemovalPolicy.RETAIN,
  readCapacity: 10,
  writeCapacity: 10,
  pointInTimeRecoverySpecification: {
    pointInTimeRecoveryEnabled: true
  }
});
