---------------------------------------
Hi Stephane, no problem we'll be able to talk about this next week ;)
I agree point 4) is not a great deal I'm just trying to analyse all details. I'm
still not convinced about hashing. If ideal hashing algorithms could be implemented, we
could write the inverse function of them, and this would proof that any information could
be compressed in a smaller form - against Shannon's source coding theorem - and
ultimately I could encode any information into "0" or "1", clearly
absurd. Definitely, a high quality hashing implementation has a low ratio of collisions,
but zero collisions is impossible. Of course, we could agree that an int has enough space
for this being kinda unlikely.
Only index an entity when it's index properties have physically
changed
