gRPC compression/decompression guide #34366

Closed eottabom closed 2 months ago

eottabom commented 4 months ago

Title: I need a guide for gRPC compression/decompression.

Description: The filter for compression/decompression works only for http1.1. I would like to know about the guide or method for gRPC compression/uncompression.

If envoy knows proto, it seems that compression and decompression are possible.

I think it will be possible with WASM filter another way.

I don't believe Envoy supports grpc compression/decompression at the moment. For non-transcoding cases it shouldn't matter as the payload is passed through. For transcoding, only uncompressed payloads are supported. I agree that a custom http filter should be able to handle compressed payloads, WASM or otherwise.

Is grpc compression/uncompression not allowed in the Envoy document?

If not, I would like to add it.

It would be nice if it stated that it should be treated with the same filter as WASM. I hope that an example will be added as well.

I recommend a short document describing your plan. I think it's probably the case that this would be another http filter.

eottabom commented 4 months ago

@zuercher Is this what you want?

I think the gRPC compression on the right can be compressed and sent by the gRPC server.

I think it will be a different http filter as you say.
