Re: [rules-users] Jbilling Drools performance

My advice is to try just having a single column: strValue matches “$param.*” you could also compare the performance of that to eval(strValue.startsWith(“$param”)) Also presumably you are only wanting the first matching rule in your table to fire, looking at the table below drools will fire all of the matching rules, this will mean than any phone number with prefix 5511 will be charged at 0.4 as that will be the last rule to fire.

I'm not sure how you'd do this in a decision table (it's probably pretty trivial) but in DRL you'd do: rule "makePhoneNumber" when s: String() then insert(new PhoneNumber(s)); retract(s); end With two caveats: 1) you need some conditions on the String matched if there are other Strings that don't make PhoneNumbers. 2) The rule could use a salience value higher than the pricing rules, but that isn't necessary. Actually, there's a third caveat, and it's a big one: this won't work with sequential mode. This is because the rule above would alter working memory with the expectation that the pricing rules would react to the change. If you want to use sequential mode you'll have to convert to PhoneNumber objects before hand. I understand that you're using this Jbilling package, but is there no way you can put an intermediate adapter between the two? It'd be as simple as inserting "new PhoneNumber(someString)" instead of "someString". --- On *Fri, 5/14/10, Antonio Anderson Souza < antonio(a)voicetechnology.com.br&gt;* wrote: From: Antonio Anderson Souza <antonio(a)voicetechnology.com.br&gt; Subject: Re: [rules-users] Jbilling Drools performance To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Date: Friday, May 14, 2010, 2:16 PM Dear Greg, Thanks very much for your reply. I'm using sequential mode = true Is there a way to create this PhoneNumber class, and convert the String to the PhoneNumber object inside the Drools? Because I'm using a system called JBilling and it send the phoneNumber as a String. Sorry if those are basic questions, but I'm a newbie in Drools... Thank you very much, Antonio Anderson Souza Voice Technology http://www.antonioams.com 2010/5/14 Greg Barton <greg_barton@yahoo.com<http://mc/compose?to=greg_barton@yahoo.com> > Right off the bat I'd say try to get rid of the eval usage. Can you put the phone number into an object like this: class PhoneNumber { private char digit0; private char digit1; ///...same for the rest of the digits public char getDigit0() { return digit0; } public char getDigit1() { return digit1; } } Then the conditions would look like this: digit0 == '$param' Behind the scenes hopefully this will optimize better. The use of eval won't optimize well. Are you using sequential mode? This might be a good candidate for that if setting the price does not trigger any other rules to fire. --- On *Fri, 5/14/10, Antonio Anderson Souza <antonioams@gmail.com<http://mc/compose?to=antonioams@gmail.com> >* wrote: From: Antonio Anderson Souza <antonioams@gmail.com<http://mc/compose?to=antonioams@gmail.com> > Subject: [rules-users] Jbilling Drools performance To: "Drools Users Mailing list" <rules-users@lists.jboss.org<http://mc/compose?to=rules-users@lists.jboss.org> > Date: Friday, May 14, 2010, 1:28 PM Dear All, I'm deploying a JBilling using Drools in a Telecom Carrier in Brazil, and I'm using Decision tables in xls files to execute the pricing, my pricing table has about 40.000 rules, and I'm getting a terrible performance about 1.5 minute to execute the price of each CDR (Call Detail Record) mediated.

Are there somebody using Jbilling in a similar way? Does anybody can help me?
