Subject Replication Factor and Data Centers
Date Tue, 15 Jun 2010 05:43:17 GMT
Is the clearer interpretation of this statement (in
conf/datacenters.properties) given anywhere else?

# The sum of all the datacenter replication factor values should equal
# the replication factor of the keyspace (i.e. sum(dc_rf) = RF)

# keyspace\:datacenter=replication factor
Keyspace1\:DC1=3
Keyspace1\:DC2=2
Keyspace1\:DC3=1

Does the above example configuration imply that Keyspace1 has a RF of 6, and
that of these 3 will go to DC1, 2 to DC2 and 1 to DC3?

What will happen if datacenters.properties and cassandra-rack.properties are
simply empty?
