Precautions:
Indexing can speed up data retrieval operations, but it will slow down data modification operations. The index must be refreshed every time a data record is modified. In order to make up for this defect to some extent, many SQL commands have a DELAY_KEY_WRITE item.
The function of this option is to temporarily prevent MySQL from refreshing the index immediately after the command inserts new records and modifies existing records, and the index will not be refreshed until all records are inserted/modified. When many new records need to be inserted into a data table, the function of the DELAY_KEY_WRITE option will be very obvious.
