That is not true.
Only the fields used are the ones evaluated. There is no pre-processing, they are only
touched, when the constraint itself is evaluated.
I guess i have to explain what is my problem. I have business objects
which
are directly used into the working memory. Theses BO are not entirely POJO,
some of them perform SQL queries. We used interfaces to produced a POJO jar,
which have been sent to knowledge base.
Previously we used drools in version 3, but now we use version 5.4 and we
notice a significant performance reduction.
It seems that all fields of the BO are readed even if they aren't used.
This
would not be a problem on the Drools side, something else must be forcing all field sot be
read - if you are not writing constraints to read them.
Our
rules are decision table in spreadsheet format. Each row's start with a
condition on a fields which doesn't make a SQL query, so normaly there isn't
a lot of peformed SQL queries.
