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

The amount of information in modern society is growing at a rapid rate, and there is a lot of data accumulating in it. It is expected that by 2025, more than 1/3 of the data generated each year will reside on the cloud platform or be processed with the cloud platform. We need to analyze and process this data to get more valuable information. In the future of "sma
