Hi all,
I am planning to apply PAGE compression to some of the big tables in my database (DW to be precise). These tables are fairly big with over 15 Billion rows. When I applied the compression in test environment, the whole process took around 22 hours.These tables are accessed daily with quite long running queries. My questions are
1. While the compression is being applied would there be any affect on the queries that are running? Any lock etc I should be aware of?
2. Is there a staggered approach to applying compression?
3.Any other input/feedback you might have?
many thanks
Sean
