Subj:   Re: Partitionin in Teradata 12.
 
From:   Victor Sokovin

Partitions are indeed created at the moment you create the table. I, however, don't see a problem with empty partitions. One reason people prefer not to create a lot of empty partitions for future use is to prevent problems with erroneous data. Imagine one day you will load a large portion of data with incorrect future dates. You will get a totally unexpected data distribution and clearing up the mess will be more difficult than when you just have one "junk" partition for all unexpected rows. But if you have a good Plan B for such events or you can trust the ETL validation rules then this becomes less of an issue.
