I have a database with almost 1T of free space. I want to run the compaction process to reclaim and subsequently free that space. I am aware that this process is a background process but will the level of processing required to move this volume of space to the end of the file to allow for reclamation impact system usage while this process is running. Essentially, does this process run at a low priority and use processing as available. I am trying to determine if I should run this over a weekend or can this be run at any time.
