Can we compile it ahead of time?

[River2000i]

sure, for now every db compile once.
if we compile once need to update the interface, i think it is not a good idea🤔

GetAllNameToIDAndTheMustLoadedTableInfo(dbID int64) (map[string]int64, []*model.TableInfo, error)

for _, di := range schemas {
		// if the ctx has been canceled, stop fetching schemas.
		if err := ctx.Err(); err != nil {
			return err
		}
		var tables []*model.TableInfo
		var err error
		if vardef.SchemaCacheSize.Load() > 0 && !infoschema.IsSpecialDB(di.Name.L) {
			name2ID, specialTableInfos, err := m.GetAllNameToIDAndTheMustLoadedTableInfo(di.ID)
			if err != nil {
				return err
			}
			di.TableName2ID = name2ID
			tables = specialTableInfos
		} else {
