Describe the solution you'd like
I would like Bedrock Chat to support Amazon OpenSearch Serverless NextGen Collection Groups.
My primary goal is to enable Scale-to-Zero for RAG workloads and reduce idle OpenSearch costs.
Currently, Bedrock Chat appears to create classic OpenSearch Serverless collections for Knowledge Bases. It would be very helpful if collections could be created under a NextGen Collection Group, allowing workloads to benefit from the new Scale-to-Zero capability.
Ideally, this could be configurable during deployment or bot creation.
Why the solution needed
In environments with many bots and Knowledge Bases, OpenSearch Serverless costs can become significant even when workloads are idle.
NextGen Collection Groups provide Scale-to-Zero capabilities, which can greatly reduce idle costs for RAG systems.
This feature would make Bedrock Chat more suitable for cost-sensitive development, testing, PoC, and low-traffic production environments.
Additional context
We are currently evaluating OpenSearch Serverless NextGen Collection Groups and Scale-to-Zero behavior.
While reviewing the Bedrock Chat implementation, we observed that Knowledge Bases appear to use classic OpenSearch Serverless collections.
Before implementing our own customization, we would like to understand:
- Are there any plans to support NextGen Collection Groups?
- Is there an existing roadmap item for this feature?
- Are there any known technical limitations preventing support?
- Is there a recommended approach for organizations interested in adopting NextGen collections today?

Implementation feasibility
Yes.
I would be happy to provide feedback, share test results, and participate in discussions regarding implementation approaches and validation.
