In distributed applications, occasionally, we use compression methods to save the network bandwidth. gRPC supports message-level compression on both client and server sides. Different programming languages have different kinds of ways to enable/disable gRPC compression. This article describes how to use gRPC compression in several programming languages; Go, Java, and Ballerina. Gzip compression algorithm is the most commonly used compression algorithm in gRPC, and the samples in this article also use Gzip.
gRPC Compression in Go
In Golang, there are two different ways to enable compression on the client-side and server-side. On the client-side, we have to pass a relevant compressor as an option to the RPC call. On the server side, we have to import the gRPC Gzip package to enable message compression.
