Create a Rules (jbpm) quick start --------------------------------- Key: TEIID-2290 URL: https://issues.jboss.org/browse/TEIID-2290 Project: Teiid Issue Type: Task Components: Build/Kits Reporter: Van Halbert Assignee: Van Halbert Fix For: 8.4 Rules integration! Calling rules from within virtual procedure or transformation: Logical flow something like this: For each row convert row to array or other form that can be easily passed to user-defined function (UDF) custom UDF implementation accepts array/vararg params and converts to pojo UDF injects pojo to knowledge session rules (potentially) modify pojo UDF converts pojo back to array and returns to Teiid procedure/transformation converts array back to record/row modified values available to procedure/transformation logic End Assumptions: 1. UDF is not adding or removing columns/fields 2. UDF is not changing the datatypes of columns/fields 3. overhead of starting knowledge session for each record/row is prohibitive. Need a stateful/persistent knowledge session. This may mean a rules service of some kind, preferably in-process.
