> Consider a use-case where a message has some content (say a list of IDs) that we want
to transform into a list of objects retrieved from the database. One could do this by using
the camel-sql component as a producer. However, I don't think there's good way to do this
using the camel-jpa component. 
> As a producer, camel-jpa does not support named-queries. We have some places where we
use JPA over some tables, but in use-cases like this, we switch to camel-sql for that step,
or code a processer. Workable, but a slight impedance mis-match.
> It would be nice to add support for named-query (and related options) to the producer
in camel-jpa.
