In Java, there are six different places where data can be stored:1. Register (Register). This is the fastest storage area because it is located in a different location from the other store-the inside of the processor. However, the number of registers is extremely limited, so the registers are allocated by the compiler on demand. You cannot directly control or feel any sign of register presence in the progra

. For a memory-based computing framework like SPARK, the GC problem is particularly prominent, it will cache a large amount of data in the JVM heap space, which is the data to be used in the calculation, the GC can not be removed, every time the full GC will do a global scan of the data, This is time consuming, and as the computational time increases and the heap

With storage vMotion, you can migrate virtual machines and their disk files from one data store to another while the virtual machine is running. When migrating through storage vmotion, you can place the virtual machine and all of its disks in the same location, or choose a separate location for the virtual machine configuration files and for each virtual disk. It

Storage System design threshold is relatively high, and the largest difference in the existence of computing systems is the storage system is the bearer of data, once the system fails, not only the continuity of the business is not guaranteed, more importantly, the user data will be lost. Compute node failures, resulti

Row store As shown in figure 2, the advantage of the hadoop-based row storage structure is the high adaptability of fast data loading and dynamic load, because Row Storage ensures that all the domains with the same records are in the same cluster node, that is, the same HDFS block. However, the disadvantages of row store are also obvious. For example, it does not
