interpreting the Key_len in the explain implementation plan A column in the explain execution plan Key_len is used to indicate how many bytes are in the selected index length in this query, and we can often use this to determine how many columns of the federated index are selected. Here Key_len the calculation rule of size is: Generally, Key_len equals the byte

The optimization of the real estate site is the internal optimization, because of the huge amount of information, the number of pages, internal optimization to do in place is the need for a detailed plan and serious implementation.
