nosql

TL;DR Distributed transactions are one of the hardest problems in computer science. NoSQL was a response to scalability limitation and a very high cost of traditional RDBMS. CAP theorem says in case of network partitions, among consistency (correctness) and availability, one has to be comprised in favor of the other. The first generation of NoSQL DBMS chose availability and they were eventually consistent. In theory, they will reconcile conflicts in a finite time after a network partitioning by probabilistically voting on what the data is supposed to be....
