Do you plan to do any AFR (automatic file replication) ? If so,
consider that even a one-byte change to your "big index files" will

nodes.
Marcus, what do you mean by this?
You've mis-attributed the quote, Krishna. What i meant was exactly
what i said : if you have a 5GB file on an AFR cluster, and a client
makes a one-byte change to that file, then the entire 5GB file is
re-copied to all members of the AFR cluster.
At least, that's my understanding of the situation - please correct me
if i'm wrong. :)
In a word - no. If the nodes are connected, then only the actual 1 byte
change will be replicated. If the nodes are disconnected, then the "self
heal" will copy the entire 5GB file when the nodes connect.
