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:
In the AWS Management Console, navigate to AWS CloudFormation and select the main parent AWS CloudFormation stack.
Select the Update option for the stack.
Select Replace current template.
-
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 Select Next without changing any AWS CloudFormation parameters.
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).
