MapReduce, GFS and Bigtable are the foundations of big data today.

  None of those things are new or interesting. Maps were used in the 70s and you can find a chapter about them being parrapalized in Kthuths original Art of Computer Programming.

    The original TOACP makes no mention of map parallelization. https://www.google.com/books/edition/The_Art_of_Computer_Programming/x9AsAwAAQBAJ?hl=en&gbpv=1&bsq=map https://www.google.com/books/edition/The_Art_of_Computer_Pro... Nor the second one: https://www.google.com/books/edition/Art_of_Computer_Programming_Volume_2/Zu-HAwAAQBAJ?hl=en&gbpv=1&bsq=map https://www.google.com/books/edition/Art_of_Computer_Program... Nor the third one: https://www.google.com/books/edition/The_Art_of_Computer_Programming/e3wLBAAAQBAJ?hl=en&gbpv=1&bsq=map https://www.google.com/books/edition/The_Art_of_Computer_Pro... I also searched for "parallel" and couldn't find any relevant passages to map parallelization.

  Those are good engineering efforts, but its like building a bridge vs understanding the theory of gravity. They are definitely not foundational in anywhere near the sense that bell labs was.

    Maybe Bell Labs was only foundational due to timing?
