Subject Re: Non Guaranteed Processing
Date Thu, 05 Oct 2017 02:25:50 GMT

The content [1], flowfile [2], and provenance [3] repositories all have volatile implementations
which do not persist to the file system. You reduce the overhead by removing I/O to disk,
but in the event of power loss, you will lose the data.

I am aware that Nifi provides Guaranteed processing by storing  the data in its Content Repository.
I am wondering if there was any settings which will turn off the data persistence and keep
data in memory to avoid  I/O operations.
