BTW, will it affect the HISTORY_HOT_REGIONS?

HISTORY_HOT_REGIONS

BTW, will it affect the HISTORY_HOT_REGIONS?

This struct does not affect the results of HistoryHotRegions, which has a separate struct and uses some functions to solve, such as

pd/server/handler.go

Line 1000 in 7187a7a

func (h *Handler) PackHistoryHotReadRegions() ([]storage.HistoryHotRegion, error) {

,

pd/server/handler.go

Line 1010 in 7187a7a

func (h *Handler) PackHistoryHotWriteRegions() ([]storage.HistoryHotRegion, error) {

, but it is possible to optimize the process
