Hi Laune !
Finally I am able to read 100 thousand records as rule through reading CSV.
Thanks very very much for your precious time. I would also like to thank
Mike and other guys who have contributed in this thread.
Thanks !!! :)

Out of curiosity, are you enumerating every possible combination of your
decision variables in that table? Is the decision criteria really so
fine-grained that you can't aggregate/accumulate/regress/etc... them in a
more structured way?

Please don't let me stop you implementing Wolfgang's solution... I'm sure that
it is the best solution for implementation in a rules engine.
I was just thinking "outside of the box" for a moment.
However, if you are not comfortable with coding outside of a rules engine then
by all means ignore m

Hi Laun
Tnks for dis wonderfl solution ...I guess our performance issue is solved
as of now..But I got a small query over it.
1) When 10k records were there in the DT, the DT was to compile and all
these 10k rules now stays in the production memory.And we were inserting a

Hi Chris !
If you can elaborate it more, I will really try to implement it. I was just
started giving a try to Laune's way.
thanks !!

If you'll pardon the heresy...
It sounds to me like the whole thing can be solved with an appropriately loaded
hashtable without any need for a rules engine at all!

Hi Laune,
Thanks very much for your response. We would like to try and implement
Option 3.
We assume that the implementation involves setting up individual rows in the
excel as a collection of objects and using the From keyword to look up the
output value/row we want based on the input parame
To me, the problem discussed in this thread highlights a deeper problem (more
than DT compile time) : using DT as data storage is bad.
Wolfgang's post demonstrate this fact.
Previous posts demonstrate another problem : having 50k, 100k rules with the
very same (basic) structure demonstrate that
The problem discussed in this thread arises from a spreadsheet where 6
values are to be matched (==) with fact object properties, resulting
in the setting of a single attribute in the field. The spreadsheet has
26400 lines, resulting in so many rules that merely differ in the
values of the literals
*Hi Vincent !
50k records is very less for the projects scaling over 1 lac(100k) records
and when I started working on Drools, I was assured with performance and
ease in developing business rule. But if xls format(DTs) not even supporting
26k records , how can I implement it for client requirement
again .

Hi Laune and thanks for replying !
We have a set of Insurance Rate Tables setup as Drools Decision tables. One
of these is large – 50,000 rows – These are setup as individual line items
in a single Decision table [four parameters whose input value leads to a
result value]. We notice that while lo
You have to distinguish between the time required for building the
KnowledgeBase from the decision table, and the time required for
processing a fact with the 50,000 rules.
If the former is the problem, serializing the KnowledgeBase is the best
you can do, and you don't need Hibernate.
If the lat
Hi Mike and thanks for replying !
Actually I am planning to store rules in database because calling from excel
sheet effects performance drastically. So kindly guide me to migrate excel
sheet rules to database using Hibernate or please suggest me other possible
options.
Thanks !!

Your requirement is not clear.
What do you want to store in a database? Rules, Facts?
Is "50,000 records in one of my decision tables" 50k rows or 50k facts?
If facts what makes you thinking moving them from in-memory objects to a
database will bring any performance gains?

Hi All !
I want to use Hibernate for database persistence in my drools project.
Please suggest me the steps. I am using 5.4.0 final version. Which version
of hibernate I shall use whether 3.1 or Annotation one.?? I have idea
about 3.1. Actually I am having 50,000 records in one of my Decision
