Hi Everyone, Grouping on high cardinality column, we are observing discrepancy in results. We have already disabled the Server level group trimming at query level . OPTION(minServerGroupTrimSize=-1) Also in result metadata numGroupsLimitReached = false, so at segment level, threshold is not breached. Any other options to explore ?
