The Shared Nothing Architecture is a relatively old pattern that has had a resurgence of late in data storage technologies, particularly in the NoSQL, Data Warehousing and Big Data spaces. The capacity of a Storage Node serves as a rough measure of the hardware resources associated with it. The data can be structured, but NoSQL is used when what really matters is the ability to store and retrieve great quantities of data, not the relationships between the elements. The term NoSQL (or Not Only SQL) became prominent in the late 2000s because the amount of data collected and used by popular web services began to increase exponentially. The author does assume some programming knowledge but does not require any single language. DevOps. According to Purdy, most of the operations that one can perform on a relational (SQL) database are either impossible or impossibly-slow using a NoSQL database, and tend to get worse as the NoSQL database is scaled out. It comes down to: to keep data integrity and support transactions, a multi-server RDBMS would need to have a fast backend communication channel to synchronize all possible transactions and writes, while preventing/handling deadlock.
