Considered adding a Serverless version of the OpenSearch service?

[fankaibo]

I have read the complete introduction of v0.2.5. I saw that even if I don't use it, there will be a fee of $100/month.
This fee is incurred when the node of OpenSearchService is running.
For users who only want to use it in meetings (maybe 10 meetings per month, 1-2 hours per meeting), $100 is a relatively high cost.

Is it possible to add a Serverless version option to the OpenSearch service to further reduce the cost?

Hi,
LMA uses the QnABot to power the meeting assistant.. See https://github.com/aws-solutions/qnabot-on-aws
For enterprises with many users, the opensearch cost is shared across all users, and so it's not so much of an issue.
However, I agree this is a good request.. In fact I think QnABot should not only support serverless OpenSearch, but ideally be able to share an instance with Bedrock Knowledge base, so that when both are provisioned they can share the same OpenSearch to save on cost. Can you create a new feature request in the QnABot repo for this, and cross link it with this one.. Thanks!
