Answer / Aprajita
In Apache Cassandra, a column family is the equivalent of a table in relational databases. It consists of rows (similar to records), columns (fields within each row), and supercolumns (a group of columns that share the same column name). Column families are organized hierarchically by using supercolumns and can be designed with different configurations such as data compression, compaction strategies, and replication settings.
