The "after 20 facts or so" makes me think that some constraint behaves
differently when jitted
(constraints are jitted lazily, to go from interpreted to compiled mode,
only when they are used
often enough).
In fact, there was a bug that was fixed a few days ago regarding a
different behavior of "contains".
The interpreted version would work as String.contains, while the
compiled version would work
as Collection.contains - or vice versa, I don't remember right now.
Unfortunately, the fix can't be backported to 5.5.0.Final.
Can you try to rewrite constraints like :
_name:catalog['name'] not contains 'Timer'
into
_name:catalog['name'], ! ((String) catalog['name']).contains( 'Timer' )
and see if the situation improves?
On a totally unrelated topic...
I have also noticed that you have a very peculiar data model..
we developed traits in 5.6 and 6.x to deal with relational models like
yours..
would you be interested in doing some research and see if/how they
impact performance and rule authoring?
