| D | README.md | 1 ## Compression with gRPC Python
3 gRPC offers lossless compression options in order to decrease the number of bits
4 transferred over the wire. Three levels of compression are available:
6 - `grpc.Compression.NoCompression` - No compression is applied to the payload. (default)
7 - `grpc.Compression.Deflate` - The "Deflate" algorithm is applied to the payload.
8 - `grpc.Compression.Gzip` - The Gzip algorithm is applied to the payload.
10 The default option on both clients and servers is `grpc.Compression.NoCompression`.
12 See [the gRPC Compression Spec](https://github.com/grpc/grpc/blob/master/doc/compression.md)
15 ### Client Side Compression
17 Compression may be set at two levels on the client side.
