- Source: Generated code
- Type last changed: v2.93.0 · 23 Aug 2023

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_lambda as lambda } from 'aws-cdk-lib';
const documentDBEventSourceConfigProperty: lambda.CfnEventSourceMapping.DocumentDBEventSourceConfigProperty = {
  collectionName: 'collectionName',
  databaseName: 'databaseName',
  fullDocument: 'fullDocument',
};
```

## Properties

- `collectionName`: string — The name of the collection to consume within the database.

  If you do not specify a collection, Lambda consumes all collections.

- `databaseName`: string — The name of the database to consume within the DocumentDB cluster.

- `fullDocument`: string — Determines what DocumentDB sends to your event stream during document update operations.

  If set to UpdateLookup, DocumentDB sends a delta describing the changes, along with a copy of the entire document. Otherwise, DocumentDB sends only a partial document that contains the changes.
