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

mapping file class _ossmmapfile is actually managing a memory map of a file, because some database files can be very large, if you want to map the database file directly to a contiguous virtual address space, it is possible to map the failure, so _ Ossmmapfile is the mapping of files to multiple memory segments, and each memory segment corresponds to a _ossmmapsegment type object. All data segments mapped to memory are placed in a collection (Std::ve

Instantaneous data refers to data that is stored in memory that may be lost due to program shutdown or other causes of memory being recycled. This is absolutely intolerable for some critical data information, and no one wants to have just sent out a microblog, refreshing it. So how can you ensure that some critical data
