@egor-ryashin Thanks for opening this PR. If I understand correctly, this PR tries to addresses #11042, #11140 and #11567. There was a discussion about this problem, and I left [some comments](https://lists.apache.org/thread.html/rc659b7c681499911fb6eff46b9edb5a3d983c11d0c253909afc905b1%40%3Cdev.druid.apache.org%3E) on the dev mailing thread. One problem is that LIMIT/OFFSET is not used by the WebUI to limit the task count returned by the server. But the core problem I think is that the overlord retrieves all task records from the metadata storage to the SQL layer, the performance bottleneck might be here. So I guess limiting the task count might be less help as we expect. But if want to limit the count at the SQL layer to make a try, I think it's better to do it at the WebUI side by using LIMIT/OFFSET clause instead of introducing a new configuration at the server side. -- This is an automated message from the Apache Git Service.
