This http://wiki.apache.org/cassandra/Operations#Token_selection says:
"With NetworkTopologyStrategy, you should calculate the tokens the nodes
in each DC independantly."
and gives the example:
DC1
node 1 = 0
node 2 = 85070591730234615865843651857942052864
DC2
node 3 = 1
node 4 = 85070591730234615865843651857942052865
So, according to the above, the token ranges would be (abbreviated nums):
DC1
node 1 = 0 Range: (8..4, 16], (0, 0]
node 2 = 8..4 Range: (0, 8..4]
DC2
node 3 = 1 Range: (8..5, 16], (0, 1]
node 4 = 8..5 Range: (1, 8..5]
If the above is correct, then I would be surprised as this paragraph is
the only place were one would discover this and may be easy to miss...
unless there's a doc buried somewhere in plain view that I missed.
So, have I interpreted this paragraph correctly? Was this design to
help keep data somewhat localized if that was important, such as a
geographically dispersed DC?
Thanks!
