Overview

Enumerable view of every registered loop. Reads ‘periodic` SET + `loops:lid` HASH on each iteration — cheap because the dashboard’s list view is the only hot caller.

Constructor Details

#initialize(config = nil) ⇒ LoopSet

‘config` scopes Redis to that config’s per-fork pool — the leader poller runs inside a swarm child and must not reach for the parent-inherited global socket. Dashboard/CLI callers pass nothing and get Wurk.redis.
