Should we rename these `defaultBackPressureObjectThreshold` and
`defaultBackPressureDataSizeThreshold`? Also, we can make the
`defaultBackPressureObjectThreshold` a `Long`.
> Add nifi.properties value to globally set the default backpressure size
> threshold for each connection

> Assignee: Michael Moser
> Priority: Major
>
> 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.
