Essential Python Lib This section describes various types of libraries commonly used by Python for big data analysis. Numpy Python-specific standard module library for numerical computation, including: 1. A powerful n-dimensional Array object Array; 2. Mature (broadcast) function libraries; 3. toolkit for integrating C/C ++ and Fortran code; 4. Practical linear algebra, Fourier transformation, and ran

For a long time, large data communities have generally recognized the inadequacy of batch data processing. Many applications have an urgent need for real-time query and streaming processing. In recent years, driven by this idea, a series of solutions have been spawned, with Twitter Storm,yahoo S4,cloudera Impala,apache Spark and Apache Tez to join the big
