---------------------------------

             Summary: Limit max count of rows filtered per scan request.
                 Key: HBASE-28107
                 URL: https://issues.apache.org/jira/browse/HBASE-28107
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 3.0.0
            Reporter: zhuyaogai


In some scenarios, when users do not understand the impact of the filters they 
set, it may lead to a large number of rows being filtered, causing very high 
CPU usage and system load, which may affect the requests of others. Therefore, 
we need to have the defensive capability to detect and kill such abnormal 
requests.
