Subject In a PE how do I know which Keys are getting sent to me?
Date Wed, 16 Nov 2011 19:32:41 GMT
Here is a scenario:

DBSinkPE- writes the event to the database.
DBKeySelector- based on the event id picks which db to write to.

The problem is simple sharding by using modulus. In the PE I need to know
which key the event belongs to so I can create the right jdbc url.

#1 I can call the KeyFinder again... seems clunky.
#2 I can mark the event with the Key in the KeyFinder... probably works.

#3 some elegant method you will tell me...
