storage engine needs an optimal way to parse the join statement efficiently. Developers need to rack their brains to write query statements, and then the database parses them.This is why a lot of developers who pay attention to the speed of operation abandon the data table instead of using the nonstandard data tables. Do not differentiate between data entities and save all data to a large table--to avoid complex queries. This is really fast, and the server does not run out of memory.Disk space
