dang-stripe opened a new issue, #17565: URL: https://github.com/apache/pinot/issues/17565
Multistage operators like aggregate (num_groups_limit), join (max_rows_in_join), and window (max_rows_in_window) have limits that will lead queries to fail when they are hit. There are server metrics to track when they are exceeded, but none to track how close queries are to the limit. https://github.com/apache/pinot/blob/master/pinot-common/src/main/java/org/apache/pinot/common/metrics/ServerMeter.java#L157 The only other way to fetch this information is by reviewing stage stats. Ideally servers expose metrics to track % of the limit so operators can monitor them so we can tune the query or scale the tenant as needed. -- This is an automated message from the Apache Git Service.
