Joe Luo updated CAMEL-1534:
---------------------------

    Attachment: Camel-1534.patch

Hi, Claus

Here is the patch for this issue. I added an option "routeEmptyResultSet" onto polling consumer so it will not send an empty resultset to the next hop by default. 

However, if an iterator is used ("useIterator=true"), the "routeEmptyResultSet" won't have any effect as the empty list will not contain any individual object at all.

> The camel-ibatis component routes any result from the database so if a SELECT query returns 0 rows Camel will route an exchange.
> We should add an option to iBatis to allow end users to filter out empty results so Camel only route an Exchange if there are > 0 rows.
