Could you build this?

No Implementing Postgres-style pub/sub semantics across SQLite requires deep systems programming, handling cross-process synchronization, OS primitives (e.g., shared memory, pipes, or file locks), and database internals. AI coding assistants struggle with high-concurrency race conditions and low-level IPC state machines.

What it would actually take: A production implementation requires systems programming in Rust or C, utilizing OS-level IPC mechanisms (shared memory, POSIX semaphores, or kqueue/epoll) alongside SQLite triggers or WAL hook monitoring. The hard part is ensuring transactional guarantees (delivering notifications strictly on commit and discarding on rollback) without blocking concurrent SQLite readers or writers.

Discussion

20 comments analyzed.

Competitors mentioned: update_hooks (SQLite C API), Postgres listen/notify, Postgres + SQS setup

Concerns raised: CPU/battery impact of 1ms polling on low-power devices, Performance overhead of going through VFS layer vs C API, Behavior under high write contention, File replacement/atomic rename edge cases

Feature requests: Use inotify(7) to eliminate active polling, Support as CRUD message stream for downstream consumers
