Based on distributed k-prototypes algorithm design Li Clustering algorithm has been widely used in many fields, for most datasets, the properties of which are not exactly numerical type, which brings difficulty to clustering. The emergence of K-prototypes algorithm solves the difficulty of hybrid attribute clustering, but its calculation is tedious and brings a lot of difficulties to programmers. The emergence of the Hadoop distributed system provides the possibility for compiling the parallel k-prototypes algorithm, which can improve the program parallelism and greatly improve the program ...

The initial key value comparison, MongoDB victory faster, and this has always been our goal to give the database system MySQL dragster the speed of the disk as its biggest obstacle, this really can make sense? Let's just make an obstacle, what about the solution? If an obstacle limits your dragster, you can choose to bypass it faster or improve on the computer. For example: Avoid the use of disk, as much as possible memory in lieu of faster disk (such as SSD) in fact, this is not good analogy, because the limit from the disk is like ...
