Mark Payne commented on NIFI-626:
---------------------------------
Toivo,
In your DBCPServiceSimpleImpl class, you are returning null for the service
identifier. Service identifiers cannot be null. I recommend changing that class
to just extend AbstractControllerService. Should make your life a lot easier :)
Thanks

> For example query can be:
> SELECT * FROM orders WHERE orderId = '${order.id}'
> where ${order.id} is FlowFile attribute.
> Result will serialized using Avro.
> Avro gives as possibility to have query Resultset metadata (column name and
> types) included in FlowFile.
> Also Avro should allow streaming.
