Nov 27 15:06:01 [27156]: [2017-11-27 15:06:01] [10.45ms] SELECT * FROM `executions` WHERE `executions`.`name` = 'test1' AND `executions`.`region` = 'idc' AND `executions`.`group` = '0' AND `executions`.`run_node_name` = '' AND ((`name` = 'test1') AND (`region` = 'idc')) ORDER BY `executions`.`name` ASC LIMIT 1
When insert executions into databases, it will execution this sql, may be AND ((
name = 'test1') AND (
region = 'idc'))

When a job needs to be executed on 97 agents, the CPU utilization of the job scheduling node can reach more than 70% (2.40GHz intel core2 duo cpu). The CPU utilization needs to be reduced below 40%
Tags can only be read from the configuration file is not flexible. Tags can set by APIs, and store the tag to somewhere
As agnet will perform an RPC call each time to run the job to obtain the job information, which led to the database periodically concurrent spikes.
A job executing on a large number of nodes at the same time will cause excessive concurrency to other systems on which the job itself depends, requiring a way to control the concurrency of the job.
