----------------------------------

Ricky,

What do you think would be good to do with the responses from SQL queries - how/what should we serialize?

Thanks
Joe

> This could be very useful for a variety of tasks, such as updating a value in a PostgreSQL table, or adding a new partition to Hive. 
> Ideally, SQL commands could be generated using the NiFi expression language using FlowFile attributes. 
> The processor should as generic as possible so that any of the popular JDBC drivers can be used (e.g. PostgreSQL, Hive, Impala). 
> I'm still new to how processors are architected, but it seems that using a pre-defined service in the _services.xml_ file (like the distributed map cache) would be the most efficient way to share a connection pool across multiple JDBC processors.
