Hi, As James mentioned in your example the "system" memory would be used by the process/script in this case.
I wanted to add that if you use the "ExecuteScript" processor that the NiFi memory would be used. This is because NiFi uses Jython for processing Python files. So where a native Cython process would typically create a heap for a Python objects in a native process, Jython will instead use the Java heap Jeremy Dyer On Wed, Sep 14, 2022 at 8:36 AM James Halfpenny <j...@source321.com> wrote: > Hi, > The memory you allocate to NiFi will typically be the maximum heap size > for the Java process.
