Algorithm for distributing key of Cassandra
Dear all,
At the blog of JONATHAN ELLIS, he said that Cassandra use a hack (trick) for
distributing key for each node. But the link point to that document is not
available.
Could you tell me more about that algorithm?
Thank

Ah, right. Unfortunately the old google groups for Cassandra are
deleted, hence the broken links.

I guess this is the related post
http://spyced.blogspot.com/2009/05/consistent-hashing-vs-order-preserving.html
thought I believe the original poster misphrased or misread (the hack
in question was assigning multiple tokens to nodes for load balancing,
which cassandra does not).
The two links in the second paragraph are broken, I remember this
cause I had been curious to read them too :)

Doesn't ring a bell. Maybe if you included the link to which you refer?
