Give the differences between the different types of primary keys in cassandra?
Answer / Preeti Gangwar
Apache Cassandra offers three types of primary keys: 1) Partition Key - a column that determines where data is stored and how it's distributed across nodes. 2) Clustering Columns - further partition data within a single partition key, used for secondary indexing. 3) Composite Primary Key - consists of multiple columns as the primary key, allowing efficient data organization and query optimization.
