Need to know weather this is possible in any Talend Module, there are some set of rules defined and can change at regular interval of time rules (if and else for example). now without a single change in the talend job, these rules need to set and talend job has to accept that new set of rules and work accordingly.
eg: this is acheivable in Oracle SOA.
Could you please give us more information about your job requirement? Are you referring to BPEL job?
