is relatively small and the running speed is definitely not fast, like a tortoise. I hope you will not laugh at this.

. This provides the possibility of concurrent INSERT, UPDATE, and DELETE operations. Unlike MyISAM, the next operation can be performed only after an operation is completed.At the same time, InnoDB also provides the foreign key function. This ensures that the data in table 1 exists before you insert data into table 2. In addition, this will prevent you from deleting the data that table 2 depends on in table 1
