turns out pg-boss is not using LISTEN/NOTIFY with Postgres, which makes it a polling queue management system. This means we need to tune the polling interval. The minimum is 0.5s, so I set it like so. I believe this shows we need to drop pg-boss altogether. Signed-off-by: Gal Schlezinger <gal@spitfire.co.il>

Since LISTEN/NOTIFY was requested in 2017 but never implemented, might be worth considering Graphile Worker which uses it natively: Graphile Worker benchmarks show it's able to handle ~2.6ms avg latency while processing ~11,800 jobs/sec The public API wouldn't change since it's internal to world-postgres. However, it would be a breaking change for users already running pg-boss in production (different DB schema, existing jobs won't migrate). Would need a major version bump with migration docs. Thoughts? Would be happy to work on this |

Just noticed #332 introduces a QueueDriver abstraction that would make adding Graphile Worker much cleaner. Instead of replacing pg-boss entirely, it could be added as an alternative driver |

@alex-holovach Good thinking. I'll ping the author of #332 to see if they want to continue on their solution. In the meantime, I'll merge this PR. |
i just used pg boss because it seemed to be more widely used, but indeed a bad decision on my part: @copilot
