@markap14 and @mcgilman I did consider that backpressure settings didn't
really belong in AboutDTO. The BannerDTO also pulls information from
nifi.properties, but I didn't think backpressure fit there either. I didn't
want to further expand the API by adding something like BackpressureDTO at a
/nifi-api/flow/backpressure endpoint, but maybe that's the preferred approach?
Or perhaps a PropertiesDTO at /nifi-api/flow/properties to do something more
generic?
> Add nifi.properties value to globally set the default backpressure size

> By default each new connection added to the workflow canvas will have a
> default backpressure size threshold of 10,000 objects. While the threshold
> can be changed on a connection level it would be convenient to have a global
> mechanism for setting that value to something other than 10,000. This
> enhancement would add a property to nifi.properties that would allow for this
> threshold to be set globally unless otherwise overridden at the connection
> level.
