DevConf 2014: Andrei Aksenov, author of Sphinx - will tell you how the repositories are arranged inside NoSQL

If you already know what B + tree, Fractal tree, LSM, SSTable, columnar storage, Bloom filter, read / write amplification are, what the No letters in the word NoSQL mean, how miraculously the stonewall bases press data 100+ times, and why the file on the disk is also NoSQL, only small and evil, you have absolutely nothing to do on this report. For everyone else, we will give a brief overview of the entire flower format of different data storage structures used in modern post-relational databases and, of course, we will try to further confuse the answers to the main questions of existence (“So will SQL or NoSQL win?”, “What database should we take? " Etc. )
