> @liukun4515 I have added more functions and am planning to add a few in the next few days. Here are the list, please add as tasks: > > covar(col1, col2): calculate the covariance (sample) of col1 and col2 > > covar_samp(col1, col2): calculate the covariance (sample) of col1 and col2 > > covar_pop(col1, col2): calculate the covariance (population) of col1 and col2 > > corr(col1, col2): calculate the correlation coefficient (sample) of col1 and col2 > > corr_samp(col1, col2): calculate the correlation coefficient (sample) of col1 and col2 > > corr_pop(col1, col2): calculate the correlation coefficient (population) of col1 and col2 > > median(col1): calculate the median of col1 @realno The list of function are not agg function, and they are the builtin-function for datafusion. Now the decimal is not supported in the builtin-function. I will support them with decimal data when refactoring this model. I will file a new issue to track builtin-function. -- This is an automated message from the Apache Git Service.
