From 1983 to 1986, the mythical physicist and instructor Richard Feynman gave a direction at Caltech known as “Potentialities and barriers of Computing Machines.”Although the lectures are over ten years outdated, many of the fabric is undying and offers a “Feynmanesque” evaluate of many usual and a few not-so-standard issues in computing device technology. those contain computability, Turing machines (or as Feynman stated, “Mr. Turing’s machines”), details concept, Shannon’s Theorem, reversible computation, the thermodynamics of computation, the quantum limits to computation, and the physics of VLSI units. Taken jointly, those lectures characterize a distinct exploration of the elemental boundaries of electronic computers.Feynman’s philosophy of studying and discovery comes via strongly in those lectures. He continuously issues out some great benefits of being silly with ideas and dealing out ideas to difficulties in your own-before taking a look at the again of the publication for the solutions. As Feynman says within the lectures: “If you retain proving stuff that others have performed, getting self belief, expanding complexities of your solutions-for the joys of it-then someday you’ll flip round and discovers that no-one truly did that one! And that’s tips to turn into a working laptop or computer scientist.”

Query responses from Hadoop and Hive are predominantly batch operations, which are designed and expected to be time consuming and no-way close to real time. But there are scenarios that businesses demand, where they need real-time answers to their queries.
