Changes to ObjectNode and NodeRevisionDescriptor for Slide 2.1
Folks!
In http://issues.apache.org/bugzilla/show_bug.cgi?id=30442 Tara probosed
patches to allow ObjectNode to track newly added and deleted children
and NodeRevisionDescriptor the same with properties. Along with that
came changes to the MySQL store that make use of them. I decided to put
the stuff to the HEAD for 2.2 and later revisions as it meant a major
change in the database store.
However, it would be somewhat handy to have the modifications in
ObjectNode and NodeRevisionDescriptor - which are pretty obvious - in
2.1 as well. I am especially thinking of custom store implementations
that could make use of the additional information.
If no one vetos I would like to take over the changes.
Comments?
Oliver

Just with this core change there will be no performance enhancements.
The stores will have to use the additional information to store more
"intelligent". Tara reported some impressive speedups with MySQL and -
most important - the time it takes to add a new child is no longer
linear to the number of children that already exists, but is pretty much
constant, I guess. I understand this is a very important step to the
maturity of Slide and I hope stores will soon catch up with this
development.
Anyway, I wanted to have at least the core feature in 2.1 to allow at
least custom stores to benefit from it.
Like with the "connection reset by peer" thing in the GET method I will
wait until tomorrow for more feedback and if there are no vetos I will
make the changes...

I think with a second beta release thats no problem.
Have you any experiences about the performance enhancements?
