In the licencing discussion, I mentioned that we really need more user feedback before we release 10.2. Discussion has occurred on the developer list on that point and is on this thread. http://www.nabble.com/10.2-plans-%28was-Re%3A-10.2-licensing-issue%29-tf2256208.html

The summary is that right now the development community is not in a position to work on any known regression and we should release to motivate users to try 10.2. Kathy Saunders probably summed it up the concern best when she said:

"If we really believe we need more testing, then what is that testing and who is going to do it? "

My opinion is that our overall confidence in the quality and robustness of Derby needs to increase release to release and we should feel confident about that and should communicate risk in areas that are likely impacted in terms that users can understand so you can either adjust your expectations or do your part to bring your expectations back to their prior level. Whether you count on Derby to control your I.V drip, use it in the critical path of your business, or just use it to manage your CD collection, you have the right to know the information and can then assess whether you want to take your necessary role of flushing out optimizer issues, before or after the release. The summary is this:

There were significant optimizer performance changes in 10.2 that are taking queries that were running for hours to seconds. (Maybe someone can point to the data). These changes involve the optimizer and it is really not possible to have comprehensive regression tests in this area. The changes in my opinion are worth while, high quality, risky and regression prone. We have had optimizer feedback from a single user who exposed several issues. Other issues have been exposed by development. We have fixed what we can. We need users especially those who have complex or performance sensitive queries to try their existing applications and give us feedback. Army can you please give an overview of the changes from a functional perspective and explain what types of usage you think could pop issues? Also I would like your opinion on the value of such testing from the user community?
