Subject [Cassandra Wiki] Update of "StorageConfiguration" by tuxracer69
Date Mon, 16 Nov 2009 18:48:00 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.

The "StorageConfiguration" page has been changed by tuxracer69.
The comment on this change is: InitialToken .


+ Cassandra uses MD5 hash internally to hash the keys to place on the ring in a {{{RandomPartitioner}}}.
So it makes sense to divide the hash space equally by the number of
+ machines available using {{{InitialToken}}} ie, If there are 10 machines, each will handle
1/10th of maximum hash value) and expect that the machines will get a reasonably equal load.
  == EndPointSnitch ==
  !EndPointSnitch: Setting this to the class that implements {{{IEndPointSnitch}}} which will
see if two endpoints are in the same data center or on the same rack. Out of the box, Cassandra
provides {{{org.apache.cassandra.locator.EndPointSnitch}}}
