<div class="gmail_extra">Hello,<br>about your point #1, you can use status of rules and therefor only build in production if a rule is in special case, but is is tricky and there is no merge facility and possibility in Guvnor. The only way is to do it from whithin eclipse with the the guvnor plugin over webdav.<br>
about your point #2 : I just finished a project with over 100k rules (huge decision tables). Building the projects take a few minutes (I was in a virtual environment which is not a good idea for this case), building the knowldgebase from Guvnor => 30s and getting a new knowledge session, like usual, not measurable<br>
about your point #3 : it works fine with mysql and postgresql, as I tested it.<br>regards<br>Nicolas Héron<br><br><div class="gmail_quote">2012/4/23 Michael Anstis <span dir="ltr"><<a href="mailto:michael.anstis@gmail.com" target="_blank">michael.anstis@gmail.com</a>></span><br>

<p>1) Guvnor uses an optimistic lock at the asset (e.g. decision table) level. We do not provide for merging as you describe.</p>
<p>3) Guvnor uses Apache Jackrabbit for persistence. Jackrabbit can be configured to use a database however the schema Jackrabbit uses is not specialised for Drools and hence querying as you might like is next to impossible.</p>
<p>One of the core Drools engine developers, or community, may be able to advise re: #3.</p>

Hello,<br>
<br>
Recently i started playing out with Drools Guvnor GUI and created couple of<br>
rules based on DecisionTable<br>
GUI Editor and also ruleflows in eclipse.<br>
<br>
Then integrated Drools with Java Custom Web Application and tried out<br>
executing rules on front end by changing rules on the drools guvnor at run<br>
time. All seems to be working fine as per expected.<br>
<br>
But i have couple questions would like to ask related to performance and<br>
maintainability of the drools.<br>
<br>
Questions:<br>
<br>
1) does drools guvnor provides any option to make revisions for the decision<br>
tables ?<br>
(Eg. If more than single developer working on the same decisiontable and<br>
making modifications to it then<br>
it should allow to merge all the changes into main one.....)<br>
<br>
2) how to measure performance of the drools to make it work and available<br>
for the large rule datasets?<br>
<br>
3) There are options to store data in a different formats like repository<br>
(default one), Oracle, mysql.....etc<br>
which one is better if i want to make my data backup very easily and import<br>
it back whenever i need ?<br>
<br>
4) is it drools is good one to replace with Yasu?<br>
