Subj:   Re: Drop Stats before loading data ?

  I would like to know whether stats must be dropped before loading data using mload or fastload .  


It is not mandatory to drop stats, however, if after loading the data, the table has been extensively added to (>10% of rows added), the optimiser would generate poor access and join plans based on the old / out of data stats. Therefore, statistics should be refreshed (or dropped) in this case.
