I confirmed my host machine has only TWO NUMA availability through numactl command.
However, I am curious about the impact if I create more nodes then two.
I already tried to create 4 nodes per host and it worked much faster regarding data ingestion and transaction processing.
Please refer to the server specification below.
4 hosts (28 CPUs, 192GB Mem, 1TB Disk) > 1 host(1MA, 3CA), 3 hosts(12 Leaves)
