With a procedure per stats model, the user have to invoke procedure/action for every stats and also with any new stats addition, the user need to ensure to update his code to call the new procedure/action. > not mix it with partition stats. I think we could have partition stats as a separate action since it per partition, whereas this procedure can collect top level table stats. -- This is an automated message from the Apache Git Service.
