In my previous blog posts, I highlighted the importance of using Event Sequence as the sort key. Some of the feedback has been that sorting can be a cumbersome operation because: Using sys.fn_xe_file_target_read_file the XML has to be queried and indexed which can take time and space, followed by the order by event sequence query.
