What database backend does Quora use?
Oh interesting, do you know why they chose to use a combination of databases instead of just one?
Yes, while relational databases like MySQL are great for handling complex queries and transactions, they can struggle with large-scale data processing and storage. Non-relational databases like Cassandra and HBase are better suited for these tasks, but may not be as efficient for complex queries. By using a combination of both, Quora is able to balance performance and scalability in their system.
