This article introduces Honker, a Rust SQLite extension that brings Postgres NOTIFY/LISTEN semantics to SQLite, enabling queue and stream functionality. It supports Python bindings for enqueuing jobs and consuming them asynchronously, as well as Kafka-style durable streams with transactional outbox pattern. The extension adds custom SQL functions like notify() and honker_stream_read_since(), requires WAL mode, and uses efficient polling via stat calls. It's a solid implementation for transactional job draining in SQLite.
