请教一下mysql.lua的连接函数为什么只连接一次

[seclionys]

代码链接

    -- try connect first only once
    channel:connect(true)

如果这里不传true，那么当连接不上时会进行重试，这样会有什么问题吗？
为什么这里只进行一次连接呢？

function _M.connect(opts)
    local self = setmetatable({}, mt)

    local max_packet_size = opts.max_packet_size
    if not max_packet_size then
        max_packet_size = 1024 * 1024 -- default 1 MB
    end
    self._max_packet_size = max_packet_size
    self.compact = opts.compact_arrays

    local database = opts.database or ""
    local user = opts.user or ""
    local password = opts.password or ""
    local charset = CHARSET_MAP[opts.charset or "_default"]
    local channel =
        socketchannel.channel {
        host = opts.host,
        port = opts.port or 3306,
        auth = _mysql_login(self, user, password, charset, database, opts.on_connect),
        overload = opts.overload
    }
    self.sockchannel = channel
    -- try connect first only once
    channel:connect(true)

    return self
end

哦，看到后面query的代码，每次都会检查连接，所以这里只要保证启动的时候连接上就行了是吧
