structlog-journald, attach extra info to jogs and filter logs by it

What my project does: In a multi-tenant system, logs from various tenants are often mixed, making difficult to debug. This library bridges structlog and journald, to allow to attach extra info (like tenant ID) when writing logs. When we view logs via journalctl, we can filter by that tenant ID.
Target audience: Python developers who often debug a system of many concurent operations running.
