NoSQL is a popular database storage method. It keeps data as key-value pairs. The advantages and disadvantages of NoSQL compared with RDBMS (which uses SQL) are discussed here, using the Cassandra architecture as an example. We talk about sharding, redundancy, load balancing, compaction and other features in NoSQL databases. This allows them to scale efficiently. Looking to ace your next interview?
