Hi Rob,
Why do you say steaming is single threaded? I see a lot of background
streaming threads running, for example:
"STREAM-IN-/10.210.165.49" daemon prio=10 tid=0x7f81fc001000
nid=0x107075 runnable [0x7f836b256000]
"STREAM-IN-/10.213.51.57" daemon prio=10 tid=0x7f81f0002000
nid=0x1

Hi guys,
We have a 100+ nodes cluster, each node has about 400G data, and is running
on a flash disk. We are running 2.1.2.
When I bring in a new node into the cluster, it introduces significant load
to the cluster. For the new node, the cpu usage is 100%, but disk write io
is only around 50MB/s,
