Ryan Blue commented on NIFI-293:
--------------------------------
I'm working in the upstream Avro community to define storage specifications for
high-level types, like decimal, date, timestamp, etc. Avro is a great choice
for the output of this, so let me know if you have questions about type
representation or schema management.
> Add a JDBC Processor for executing arbitrary SQL queries

> 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.
