Subject Re: Correlation between replication factor and read/write performance survey?
Date Tue, 12 Feb 2013 01:36:45 GMT
I think higher replication only makes read easier as client can choose to read  block from
nearest node.
Writes are done using replication pipeline so client does wait for ack from all nodes but
writes to only first node. It would be interesting to see if there are any benchmarks for
delay caused by this acknowledgement.
