How many workers can a tasklist associated?

[zhangkyou]

In one worker, the worker only associate to the tasklist of groupName.
worker := worker.New(h.Service, domainName, groupName, options)

But if I had a cluster to deploy the cadence worker, every machine in the cluster run the same worker code, so there had many workers associate to the same tasklist, does this deployment matter to the workflow schedule?

In other words,can several workers polling task from one tasklist parallel?

[longquanzheng]

There is no limit on that.

Hundreds of workers should be fine. If you want more than a few thousands of workers, then you might want to enable scalable task list.
