DBOS

DBOS argues that LISTEN/NOTIFY can serve high-throughput workloads with the right design. The thread accepted the measurement but resisted the headline, noting that its 8KB notification payload limit and delivery semantics define where it fits.

The valuable takeaway is architectural rather than tribal: use notifications to signal durable rows or work, not to pretend they are an unrestricted message bus. A system that handles 60,000 events per second may be excessive for one team and inadequate for another.
