Subject Re: Node added, no performance boost -- are the tokens correct?
Date Thu, 31 Mar 2011 22:15:02 GMT
A script that I have says the following:

$ python ctokens.py
How many nodes are in your cluster? 2
node 0: 0
node 1: 85070591730234615865843651857942052864

The first token should be zero, for the reasons discussed here:
http://www.datastax.com/dev/tutorials/getting_started_0_7/configuring#initial-token-values

More details are available in
http://www.datastax.com/docs/0.7/operations/clustering#adding-capacity

The DS docs have some weak areas, but these two pages have been pretty well
vetted over the past months :)
