Doesn't streaming affect the node network?
Isn't that an issue or do you have a dedicated NIC for intra node communications? or do you just limit the streaming bandwidth?
No dedicated NICs, the link speeds are fast enough to not really worry about this.
It's also worth mentioning that in a cluster of N, to recover a node, it simply needs to stream 1/(N - 1) of the data from its neighboring nodes. So when you look at the cluster as a whole, and the strain on each node that is UP and serving traffic, it's insignificant.
Thanks.
