xueyumusic opened a new issue #3851: Support variance and stddev aggregation URL: https://github.com/apache/incubator-pinot/issues/3851 Variance and stddev are common aggregations in data statistic and analysis, maybe an improvement to support it. It includes `var_pop(population variance), var_sample(unbiased variance), stddev_pop(population standard deviation) and stddev_sample(sample standard deviation)`. Submit a pr for var_pop first, if pinot could support this, will try to implement others then since they are similar and related..
