Is it possible to customize the compression algorithm in gRPC when using C++?

[梁宪松]

golang can register a custom compressor like this

```

grpc.UseCompressor(gzip.Name)

```

In C++ there is just support of several compression algorithms:

```

ChannelArguments args; // Set the default compression algorithm for the channel. 

// gzip deflate ...

args.SetCompressionAlgorithm(GRPC_COMPRESS_GZIP); GreeterClient greeter(grpc::CreateCustomChannel( "localhost:50051", grpc::InsecureChannelCredentials(), args));

```

How to add a customize "compressor" like golang?

gRPC C++ is a wrapper over gRPC Core. All available compression algorithm can be found at https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h.

However, currently there is no way to customize compression algorithm. If this is critical to you, feel free to file a feature request on GitHub: https://github.com/grpc/grpc/issues
