I think that’s a large oversimplification of Facebook. While it’s true a lot of FB storage is MySQL backed they also created many complex systems such as: - Cassandra (based on dynamo/big table) - wrote a custom KV store named RocksDb that is open source/now a company - wrote a custom photos storage system that replaced an NFS based design - wrote another custom binary object store - wrote a custom geo distributed graph db (Tao) - wrote an in house distributed FS replacement for HDFS https://www.cs.cornell.edu/projects/ladis2009/papers/lakshman-ladis2009.pdf https://www.cs.cornell.edu/projects/ladis2009/papers/lakshma... https://www.usenix.org/legacy/event/osdi10/tech/full_papers/Beaver.pdf https://www.usenix.org/legacy/event/osdi10/tech/full_papers/... https://www.usenix.org/system/files/conference/osdi14/osdi14-paper-muralidhar.pdf https://www.usenix.org/system/files/conference/osdi14/osdi14... https://www.usenix.org/system/files/conference/atc13/atc13-bronson.pdf https://www.usenix.org/system/files/conference/atc13/atc13-b... https://www.cs.princeton.edu/~wlloyd/papers/tectonic-fast21.pdf https://www.cs.princeton.edu/~wlloyd/papers/tectonic-fast21.... https://m.facebook.com/nt/screen/?params=%7B%22note_id%22%3A10158791582997200%7D&path=%2Fnotes%2Fnote%2F&refsrc=deprecated&_rdr https://m.facebook.com/nt/screen/?params=%7B%22note_id%22%3A...
