[rules-users] Using the drools as the backend engine for a service

[Michael Rhoden]

You would likely NOT want to create a rulebase per session. Most people
create working memory per session. Rulebases should only be loaded once
per server (context) in my opinion, and you reload it as rules changes.
Loading a rulebase loads rules from a file, and orders your rete tree. For
our installation that takes several minutes.

 

Rulebase = once

Working memory = per user/transaction

Subject: [rules-users] Using the drools as the backend engine for a
service

 

Hi,

 I am planning on using Drools as the rules engine for a service that I am
building. I am considering instantiating a stateful session for every
request to the service. The RuleBase would be created when the service
starts. Is this the correct way to  go about incorporating Drools in a
service ? Is session creation an expensive process and if so are there
other efficient ways of doing so ?



Thanks 

Jai
