bharadwajrembar commented on issue #9212: azure extensions: task log kill crashes with "Not Implemented". URL: https://github.com/apache/druid/issues/9212#issuecomment-606670244 We are hit with the same for S3 on version `0.17.0`. @jihoonson We use the Router for our UI. When we go into the `Ingestion` tab, the API fires this SQL query: ``` SELECT "task_id", "group_id", "type", "datasource", "created_time", "location", "duration", "error_msg", CASE WHEN "status" = 'RUNNING' THEN "runner_status" ELSE "status" END AS "status", ( CASE WHEN "status" = 'RUNNING' THEN (CASE "runner_status" WHEN 'RUNNING' THEN 4 WHEN 'PENDING' THEN 3 ELSE 2 END) ELSE 1 END ) AS "rank"FROM sys.tasks ORDER BY "rank" DESC, "created_time" DESC ``` and it takes sometime to load. Does this query go to the Overlord? If so, is having a large number of old tasks in the metadata likely to affect performance or even potentially cause OOMs in the Overlord?
