Legacy Rust scheduler

The original BTU Scheduler (btu_scheduler_daemon) was a Rust binary distributed per Linux distribution.

The retired btu-cli 0.3.2 Rust binary — subcommands like list-jobs, queue-task-now, and test-ping are no longer available

Status: retired

Maintenance has ended. Reasons include cross-platform build burden (glibc variants, WSL, macOS) vs maintainer capacity.

Replacement

Use btu_scheduler_py — Python daemon with PostgreSQL/MariaDB support and Redis RPC.

Migration notes

• Control plane is Redis RPC only (Unix sockets removed from supported path in BTU 15.1+)
• Configuration is BTU_SCHEDULER_* environment variables, not /etc/btu_scheduler/btu_scheduler.toml
• Install and run via btu-py run-daemon

Do not start new deployments on the Rust binary.
