> Hot deployment of new/upgraded components is a critical requirement in many
> scenarios. A few suggestions are :
> 1. Hot deployment of new processors/components
> 2. Hot deployment of processors/components that are not used in current flow
> context
> 3. Rolling upgrades (in a cluster)
> "Hot deployment of new processors" has immediate benefits. For example it
> helps in two very common scenarios :
> a) Development of a complex processor that uses a few nifi services (where
> mock framework only helps partially). (might be simple in a single node!) .
> b) Complex system that can't be restarted (Or has very short maintenance time
> : a few hours each month/year). In this situation we could build "upgraded
> processor" and use them as "new processor".
