Ever tried deleting 100 million records. If you have you will know your transaction log will likely blow up, you will block all access to the table and it will generally be painful. In this session we will look at some of the techniques you can use to make this easier. We will look at how 
  • deletes and updates work and how indexes affect them
  • how to break the job into smaller chunks
  • how to run those chunks in parallel

After this session you will understand more about why these operations are painful, what you can do to make them easier to do and reduc the impact on your end users.
