Couple of points: > I have figured out a way to add interceptor in server builder to add compression with type gzip
You don't need an interceptor to add custom codec compression on the server side. Just use ServerBuilder.compressorRegistry(CompressorRegistry) <https://github.com/grpc/grpc-java/blob/master/api/src/main/java/io/grpc/ServerBuilder.java#L233> to use your own compressor registry with custom codecs (snappy and gzip) added. > But in such cases I would want server to do gzip compression rather than identity. Is this possible ? Unfortunately not because of this code <https://github.com/grpc/grpc-java/blob/master/core/src/main/java/io/grpc/internal/ServerCallImpl.java#L118>. In that case you can use an interceptor to check the accept-encoding header from the client and based on that set the snappy compression on the call only if client accepts it.
