Subject [Cassandra Wiki] Update of "AntiEntropy" by GehrigKunz
Date Tue, 12 Nov 2013 23:14:48 GMT
Dear Wiki user,

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

The "AntiEntropy" page has been changed by GehrigKunz:


  The key difference in Cassandra's implementation of anti-entropy is that the Merkle trees
are built per column family, and they are not maintained for longer than it takes to send
them to neighboring nodes. Instead, the trees are generated as snapshots of the dataset during
major compactions: this means that excess data might be sent across the network, but it saves
local disk IO, and is preferable for very large datasets.
