Big Talk About BigTable
Relational Databases have hegemony on the way data has been stored. Proponents of Relational Database emphasize on normalization for valid reasons. Maintainability, Integrity (summed up in ACID) and Security has been the primary focus of classical relational database problems. Backed by Moore’s law it was easy to theorize that processing speed would inevitably be a trivial factor over other engineering problems like consistency and integrity. In some sense that is true but hitherto unaccounted for were sites like Google and Facebook which needed to process PetaBytes of data every second in real time.
