Using Merkle trees to detect inconsistencies in data
Cassandra's AntiEntropy service uses Merkle trees to detect the inconsistencies in data between replicas. Merkle tree is a hash tree where leaves contain hashes of individual data blocks and parent nodes contain hashes of their respective children. It provides an efficient way to find differences in data blocks stored on replicas and reduces the amount of data transf erred to compare the data block

DataModel - Cassandra Wiki
Introduction Cassandra is a partitioned row store, where rows are organized into tables with a required primary key. The first component of a table's primary key is the partition key; within a partition, rows are clustered by the rem aining columns of the PK. Other columns may be indexed independent of the PK. This allows pervasive denormalization to "pre-build" resultsets at update time, rather th
