> ATS rest api is very slow when there are more than 1lakh entries if yarn.acl.enable is set to true as TimelineACLsManager has to check access for every entries. We can;t disable yarn.acl.enable as all the YARN ACLs uses the same config. We can have a separate config to provide read access to the ATS Entries.
