klog

A Kafka-protocol compatible log server and a Zig client.

Note

Status: proof of concept

Requirements

Zig — see minimum_zig_version in build.zig.zon for the required version.

To install the required version automatically (local dev or non-GitHub CI):

./scripts/install-zig.sh   # downloads the version from build.zig.zon

Then add the printed path to your PATH. On GitHub Actions, mlugg/setup-zig reads the same version from build.zig.zon.

Build

zig build

Produces both binaries:

• zig-out/bin/klog — the server
• zig-out/bin/client — the example client

Optimize options

Use -Doptimize to pick a release mode (default is Debug):

zig build                              # Debug
zig build -Doptimize=ReleaseSafe       # Optimized, runtime safety on
zig build -Doptimize=ReleaseFast       # Optimized, runtime safety off
zig build -Doptimize=ReleaseSmall      # Optimized for binary size

-Dtarget=<triple> cross-compiles, e.g. -Dtarget=aarch64-linux.

Run zig build --help to see every option.
