Demystifying Distributed SQL DB

Abstract:

Developers are building new applications, mission-critical applications at insanely fast rates, iterating through development cycles and scaling on-demand as required. These applications require data integrity, high read/write throughput, and 24/7 global availability with little or no downtime or maintenance windows require a new type of database. Older relational systems fail to meet these needs in terms of scalability, availability, resilience, or performance under load. NoSQL databases do not offer the robust functionality, standard query language, or transactional integrity required for systems of record. Monolithic applications are turning into agile microservices, and while the focus is primarily on the application layer, there remains a heavy reliance on the data layer to maintain a reliable customer experience. Distributed SQL database is a category of relational databases that combines the core features of traditional SQL and NoSQL systems, being strongly consistent while natively providing ACID transactional support across data centers, availability zones, and regions in the cloud.
