[grpc-java] Limit message size for uncompressed grpc requests

[lpt...@gmail.com]

I am looking for a way to enforce a limit on the size of the incoming requests (uncompressed). I have tried setting maxMessageSize on NettyServerBuilder, but it did not seem to work. After some debugging and searching, I found that this limit is only enforced in MessageDeframer, and only for compressed stream (from this commit: https://github.com/grpc/grpc-java/commit/15f02ba19c4a2c21afee39cb73cd0340ad2f9d1d). Does anyone know a way to set this for uncompressed requests?

maxMessageSize applies to both uncompressed and compressed sizes. This is the check that applies to the on-the-wire size, independent of whether the message is compressed.

It seems you are aware it only applies to incoming messages, so I'm not sure why you wouldn't be experiencing it working.

What version of grpc-java are you using?
