The prefork pool forks a child process that loads the full Django app (~100 MB RSS). For the single-node manager, concurrency is effectively 1 either way, so --pool=solo runs tasks in the worker process itself with identical execution behaviour and no extra process. Measured on a live hub: celery worker(196MB master)+pool-child(101MB)+ beat(63MB). Solo drops the pool child. Beat kept as a separate program (not embedded via -B) so a worker restart can't miss a scheduled tick. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
