Configuring a large memory for the database can effectively improve the database performance. Because the database is running, a region is allocated in the memory as the data cache. Generally, when a user accesses a database, the data is first read to the data cache. The next time the user needs to access the data, the data will be read from the data cache. Because reading data in the data cache is several

Background: Please leave the case and listen to the feedback from the platform team. When importing some data to the production database, the client access times out, the initial positioning is that the IO usage on the server disk is too high, and the IO will soar to 100% during data import. As a result, many slow query operations on the database lead to client r
