Recommendations of Java version and Garbage Collector for NiFi?

Expert Contributor

We were recently informed that Nifi bottlenecks tend to be, in order of occurrence:

  1. CPU
  2. Memory
  3. Disk

Is there a recommended Java version (Java 7 vs 8) and garbage collector (Concurrent Mark Sweep vs G1) ?

Actually memory is #3 in this list. You will probably be concerned with available storage space for content repository before running out of memory. E.g. NiFi, even in big deployments feels comfortable with 96GB available memory, which is below an average server RAM today.
