The "DigestQueries" page has been changed by KirkTrue: http://wiki.apache.org/cassandra/DigestQueries?action=diff&rev1=1&rev2=2 - A "digest" query is like a ready query except that instead of the receiving node actually returning the data, it only returns a digest (hash) of the would-be data. + A "digest" query is like a read query except that instead of the receiving node actually returning the data, it only returns a digest (hash) of the would-be data. The intent of submitting a digest query is to discover whether two or more nodes agree on what the current data is, without sending the data over the network. In particular for large amounts of data, this is a significant saving of bandwidth cost relative to sending the full data response.
