Detailed explanation-1: -All that data is stored in what is known as the Hive, which contains about 300 petabytes of data.
Detailed explanation-2: -The Architecture of Facebook’s Big Data platform Facebook uses Hadoop HDFS Architecture. Facebook collects data from two sources: User data is stored in the federated MySQL layer, and web servers produce event-based log data. Web server data is gathered and sent to Scribe servers, which run in Hadoop clusters.
Detailed explanation-3: -Facebook still uses PHP, but it has built a compiler for it so it can be turned into native code on its web servers, thus boosting performance. Facebook uses Linux but has optimized it for its own purposes (especially in terms of network throughput).
Detailed explanation-4: -C++: C++ is one of the fastest programming languages I have used. I prefer C++ for all the problems other than Data Science and Machine Learning. Facebook also uses C++ at the back-end because of its popularity among software engineers.
