uber-cadence 中的工作流工作者是否可以控制协程的数量？

Question

如果工作流执行时间长（比如工作流执行休眠），会不会产生大量的协程？

Answer 1

Cadence or Temporal workflow only needs a worker to generate the next steps to execute. When it is blocked waiting for an external event like a timer it doesn't consume any worker resources. So a single worker can process a practically unlimited number of workflows given that it can keep up with their execution rate.

As an optimization workflows are cached on a worker. But any of them can be kicked out of cache at any time without affecting their correctness.
