Since, indulgent and treatment Big data is a big dispute This paper surveys different approaches in real-time analytics of Big Data or near real-time in the detailed fields of application, as well as tools and techniques being used. The survey results indicate what technologies have been used in each of the fields of application and what the reason for the choice was along with the extension of future challenges of the same.
