1: Use partitioned tables to improve database performance Many of the previous processing of large amounts of data took the form of using multiple structured tables to be grouped by time, there are different data tables for data at different times, so if you want to query only one table's data quickly, if you need to cross table queries and then connect the tables to the table in a connection view, you can improve query efficiency , but at the expense of the elegance of programming and the simp

. Figure 1. The column storage index only supports scan operations So how does a column index store? Column index storage can be words too literally, or stored by columns. This process can be divided into 3 stages, first of all a bunch of rows grouped, this is called "row group", after the grouping is completed, and then split by column, and finally the column compression, as shown in Figure 2. Figure 2. The process of column storage We notic
