Updating the stream poller

The following information outlines the steps needed to update the stream poller with the latest Lambda artifacts using the AWS management console.

To update the stream poller with the latest Lambda artifacts

You can update the stream poller with the latest Lambda code artifacts as follows:

1. In the AWS Management Console, navigate to AWS CloudFormation and select the main parent AWS CloudFormation stack.

2. Select the Update option for the stack.

3. Select Replace current template.

4. For the template source, choose Amazon S3 URL and enter the following S3 URL:

   https://aws-neptune-customer-samples.s3.amazonaws.com/neptune-stream/neptune_to_elastic_search.json

5. Select Next without changing any AWS CloudFormation parameters.

6. Choose Update Stack.

The stack will now update the Lambda artifacts with the most recent ones.

Extending the stream poller to support custom fields

The current stream poller can easily be extended to write custom code for handling custom fields, as is explained in detail in this blog post: Capture graph changes using Neptune Streams.

Note

When adding a custom field in OpenSearch, make sure to add the new field as an inner object of a predicate (see Neptune Full-text search data model).
