Excluding vertices from neptune stream poller(Connecting Neptune with OpenSearch)

Filtering by label is not directly exposed in the CloudFormation stack, but you could add this into the Stream Poller Lambda function code. If you look at the NeptuneStreamPollerLambda that the stack creates, there is a file at the path of ./neptune_to_es/neptune_es_gremlin_handler.py where the logic for filtering takes place. Within that file, there is a filter_records() method. You could add the logic there for additional label filters. I'll add this to our backlog to support this natively, but do not have a timeline as to when we'll be able to address this.
