Subject Re: Cassandra data distribution and configuration settings
Date Tue, 17 Nov 2009 17:41:28 GMT
Hello TR,

Thanks for your quick reply :-)

 My 128 characted key values are distributed evenly across the "00 ..." to
"ff ..." data range.

I did not set the InitialToken value.  Is this a starting key value for each
node?

Is the InitialToken specified a string?

Thanks,
Jon
