1. if an update stats is running on a 5 million rows table for an hour or so, is there anyway to know how much work has already been done and how much time it will take for update stats to complete (other than looking at the log of a previous run)?
2. with a table with multiple indexes, is it possible to import the statistics for one index alone using optdiag?
3. what are the performance parameters which affect update stats and how can a running update stats be speedened up (other than parallelism)?
appreciate the insights.
