28. Clusters Clusters • The outermost structure in Cassandra is the cluster • Cluster is a container for Keyspaces • Sometimes called the ring, because Cassandra assigns data to nodes in the cluster by arranging them in a ring • A node holds a replica for different range of data APACHE CASSANDRA CERTIFICATION TRAINING www.edureka.co/cassandra

29. Keyspaces Keyspaces • A keyspace is the outermost container for data in Cassandra • Like a relational database, a keyspace has a name and a set of attributes that define keyspace-wide behaviour • Keyspace is used to group Column Families together APACHE CASSANDRA CERTIFICATION TRAINING www.edureka.co/cassandra

31. Replica Placement Strategy Replica Placement Strategy • The replica placement strategy refers to how the replicas will be placed in the ring • There are different strategies that ship with Cassandra for determining which nodes will get copies of which keys • There are mainly two types of Strategies: • Simple Strategy • Network Topology Strategy APACHE CASSANDRA CERTIFICATION TRAINING www.edureka.co/cassandra

33. Column Family Column Family • A column family is a container for an ordered collection of rows, each of which is itself an ordered collection of columns • We can freely add any column to any column family at any time, depending on your needs APACHE CASSANDRA CERTIFICATION TRAINING www.edureka.co/cassandra

34. CQL Table CQL Table • A CQL Table is a column family • CQL tables provide two-dimensional view of a column family, which contains potentially multi-dimensional data • CQL table and column family are largely interchangeable terms APACHE CASSANDRA CERTIFICATION TRAINING www.edureka.co/cassandra
