Is there a way to get the latency for how long it takes for a Cadence activity worker to pick up a new task?

Question

Is there any way to get the latency for how long it takes for a worker to pick up a new task or how long it takes for an activity to be picked up by a worker?

Answer 1

There are two metrics reported on client side for this:

• Activity scheduled to start latency
• Decision scheduled to start latency

The similar metrics on server is “sync match latency” and “async match latency “.

Sync match means when the task is scheduled, a worker is actively polling. So usually sync match latency can be used to measure how much load a task list is under
