Because historical data is not accessed in this database, it is analyzed in another OLAP database, therefore, historical data will be migrated to the OLAP database. A better way to migrate this type of historical data is to use a partitioned table. After partitioning by time, You can migrate the partition. Data can be

MBR partition table The traditional partitioning scheme, called the MBR partitioning scheme, is to save the partition information to 64 bytes in the first sector of the disk (the MBR sector). Each partition entry occupies 16 bytes, which contains the activity status flag, the file system identity, the start and end cylinder number, the number of magnets, the sec

During kernel transplantation today, we are going to add the NAND Flash Driver to achieve MTD partitioning. When we think of a sentence we saw in a book, we say there is no gap between each partition during partitioning, the ending address of the previous area is the starting address of the next area. However, when I look at my Development Board tutorial, the partition is as follows: Static struct mtd_parti
