Compression

Client side

The preferred method for configuring message compression on a client is to pass options when the client object is instantiated.

The two options need to be passed:

grpc.default_compression_algorithm (integer)

The option keeps the value of a compression algorithm.

Possible values for this option are:

• 0 - No compression
• 1 - Compress with DEFLATE algorithm
• 2 - Compress with GZIP algorithm
• 3 - Stream compression with GZIP algorithm

grpc.default_compression_level (integer)

The option keeps the value for the level of compression.

Possible values for this option are:

• 0 - None
• 1 - Low level
• 2 - Medium level
• 3 - High level

Code example

client = new ExampleClient("example.com", credentials.createInsecure(), {'grpc.default_compression_algorithm': 2, 'grpc.default_compression_level': 2});
