> Our goal is the scheduling capability of 10,000 tasks per second. Just imagine, if we have 10w+ tasks to schedule, this line of code adds 10w database requests. if we have 10w+ tasks to schedule, and there are `10` workers, we will see 100w+ queries to zk. In fact, the writing and reading performance level of zk is `2w`.  -- This is an automated message from the Apache Git Service.
