Hi Army,

I love reading your documents! Even if 85% of it is too
optimizer-y for me to understand, I learn a lot each time I
read through your work. So thanks!

One particular sentence from your most recent writeup stuck out
for me, as I had missed this in previous discussions about DERBY-805:

   The second thing was the fact that I created indexes on T3 and
   T4 _before_ inserting the data, which (it turns out) leads to
   outdated (if not altogether incorrect) statistics for the indexes.

Are the statistics always incorrect/outdated after inserting lots
of data into a table which has one or more indexes?

Or was there something specific about the way in which you inserted
your data which caused the indexes to have outdated/incorrect statistics?

thanks,

bryan
