[jira] [Commented] (KYLIN-4720) support htable read quota

    [ https://issues.apache.org/jira/browse/KYLIN-4720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17212088#comment-17212088 ] 

fengpod commented on KYLIN-4720:
--------------------------------

We use it in our production env， and it's value setted to 10000。It works well。When QPS on table over this limit，will throw QuotaExceededException。But in the past two years，we have only meet this exception only once。

> In order to avoid the pressure of massive queries on hbase，htable read quota is necessary。Through a new configuration “kylin.hbase.htable-quota”，we can control the read quota when the htable created。The default value of this conf is -1，means will not limit queries。You can set it to any intger greater than 0 as needed。
