Configure Python gRPC Server for Compression

[asadh...@gmail.com]

Has anyone does this? I cannot find any documentation or code demonstrating this. For my Python gRPC client, I use the following:

channel = grpc.insecure_channel('localhost:50051', options=[('grpc.default_compression_algorithm', 1), ('grpc.default_compression_level', CompressionLevel.high)])

How do I do the same for my Python gRPC server? Any help would be greatly appreciated. Thanks.

Unfortunately, compression settings are not yet fully supported in Python gRPC. However, I have work queued up for this quarter to address this gap. You can track progress on this through the linked github issue.

Okay, thanks for the update. I will follow this issue via github. For the time being, what would you recommend to reduce gRPC payload sizes with Python? From Python server to client, I changed the definition of my variable from string to bytes but that didn't make any difference in payload size. Since I'm sending huge chunks of data across the wire (GBs of data), even a small difference matters. Your input would be greatly appreciated. Thanks.

In the interim, if you're not tied to Python specifically, you could use a different implementation of gRPC that fully supports compression like C++ or Java. If you really are tied to Python, then you could do the compression yourself, using a module like gzip.
