ClusteredRedisQueue.once() method

Registers a one-shot listener on every server's queue and on the internal template.

Signature:

once(...args: any[]): this;

Parameters

Returns:

this

this queue instance

Remarks

Because registration is replicated per server, this arms one independent one-shot listener per server — so the callback may run once for each server in the cluster rather than once overall, and more as servers join. Use ClusteredRedisQueue.on() plus explicit de-registration if you need at-most-once semantics.
