Cassandra has a limit of 2 billion cells per partition, but what's a partition?
问题 In Cassandra Wiki, it is said that there is a limit of 2 billion cells (rows x columns) per partition. But it is unclear to me what is a partition? Do we have one partition per node per column family, which would mean that the max size of a column family would be 2 billion cells * number of nodes in the cluster. Or will Cassandra create as much partitions as required to store all the data of a column family? I am starting a new project so I will use Cassandra 2.0. 回答1: With the advent of CQL3
