rrdcached is unnecessary on NNA for a few reasons. Two primary reasons I can think of are:
1) there is only one rrd file per source on NNA where on XI there can be hundreds of rrd files
2) flow data is processed on NNA differently, compared to how XI processes check results, making rrdcached irrelevant for NNA
These docs explain the inner workings of NNA and better describe what is mentioned above:
