### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Description #### 背景 * 高并发场景下可能出现偶发的10min超时(集群10s超时)  ### Solution * 高并发场景集群可能因为某些后台因素(导入/compaction等 出现慢节点 * 能够确认是慢节点上的OlapScanNode变慢并且导致后续scanner都在排队 所以对于这种情况，我们可以通过scanner调度时间&scanner调度队列&集群超时空情况及时检查出慢节点，通过disable query暂时关闭其查询功能，并在5min(或者可配置)后自动恢复。 **目前这是一个提议。** ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
