Introduction to Bigtable
Learn about Bigtable and the motivation behind its creation.
From the dark ages to a renaissance for the databases
With the advent of hyperscale services such as worldwide search, online shopping, messaging, and so on, the deficiencies of the traditional databases (based on the relational data model) became apparent. These deficiencies can be grouped into two classes—scalability challenges and performance challenges.
Traditional databases are optimized for read-heavy workload, where data schema is known at the time of writing and does not change too frequently. Additionally, most implementations of relation DB engines were either based on a single beefy server or a group of servers physically nearby. Such a setup is needed to rely on
These deficiencies pushed organizations on a multi-decade quest to research and develop custom database systems. Primarily, the guiding rule was that for some specific applications, we might not need the full feature set of a relational model, and inventing a new, simpler model would enable us to get highly scalable and highly performant database systems. In this chapter, we will focus on one such system designed by Google, known as Bigtable.
