Grpc filter with split requests

[Sumukh Shivaprakash]

I want to write a grpc filter that splits a request into multiple requests and forwards to various upsstream clusters and aggregates the response before replying back to the client.

Is there an example of a filter that does something like this?

Not really. The easiest way to do this right now would be to write a new terminal filter that works like the router filter but issues multiple requests, waits for them and does the aggregation. You might be able to modify/enhance the router filter to do this, but that filter is already incredibly complicated and I would be weary of adding something like this unless it was really well abstracted.
