> 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.
