@Matt Clarke Can you explain (or maybe pointing to references) about this statement "Also keep in mind that the memory used by NiFi's dataflows can and often does extend beyond just heap"?

My heap allocation is 8GB - 24GB for total memory 32GB; I seem can't find clear explanation about Nifi high memory utilization aside from this one Thanks, Bobby ... View more
