[rules-users] Drools Performance and Maintanability

[dollanitri]

Hello, 

Recently i started playing out with Drools Guvnor GUI and created couple of
rules based on DecisionTable
GUI Editor and also ruleflows in eclipse.

Then integrated Drools with Java Custom Web Application and tried out
executing rules on front end by changing rules on the drools guvnor at run
time. All seems to be working fine as per expected.

But i have couple questions would like to ask related to performance and
maintainability of the drools.

Questions:

1) does drools guvnor provides any option to make revisions for the decision
tables ?
(Eg. If more than single developer working on the same decisiontable and
making modifications to it then
it should allow to merge all the changes into main one.....)

2) how to measure performance of the drools to make it work and available
for the large rule datasets?

3) There are options to store data in a different formats like repository
(default one), Oracle, mysql.....etc
which one is better if i want to make my data backup very easily and import
it back whenever i need ?

4) is it drools is good one to replace with Yasu?
