We must not ignore: when the data is not large, there will be slow analysis of the problem is due to the limited capacity of CPU computing.
So to synthesize my analysis, we can draw a few conclusions:
Problems with databases are limited in computing resources

First, prefaceBig Data technology has been going on for more than 10 years, from birth to the present. The market has long been a company or institutions, to the vast number of financial practitioners, "brainwashing" big data the future of good prospects and trends.

MapReduce differs greatly from MPI in its design purpose, usage, and support for file systems, enabling it to be more adaptable to processing needs in big data environments.What new met
