为什么我的MariaDB查询需要这么长时间？我该如何解决？

Question

SELECT 
    ps_customer.id_customer
    CONCAT(ps_customer.firstname," ",ps_customer.lastname) AS "Fullname"
    ps_customer.email
    ps_customer.date_add
    ps_orders.id_order
    ps_orders.id_address_delivery
    ps_orders.payment
    ps_stripepro_transaction.status
    ps_order_detail.id_shop
    ps_order_detail.product_name
    ps_address.address1
    ps_address.address2
    ps_address.postcode
    ps_address.city
    ps_address.phone
    ps_address.phone_mobile
    ps_vd_customer_dogs.name
    ps_vd_customer_dogs.size
    ps_vd_customer_dogs.breed
    ps_vd_customer_dogs.toy_destroyer
    ps_order_cart_rule.name
    ps_order_cart_rule.value
    ps_order_detail.product_quantity
    ps_message.message
FROM ps_orders
    LEFT JOIN ps_customer
    ON ps_orders.id_customer = ps_customer.id_customer 
    LEFT JOIN ps_stripepro_transaction
    ON ps_orders.id_order = ps_stripepro_transaction.id_order
    LEFT JOIN ps_order_detail
    ON ps_orders.id_order = ps_order_detail.id_order
    LEFT JOIN ps_address
    ON ps_orders.id_customer = ps_address.id_customer
    LEFT JOIN ps_vd_customer_dogs
    ON ps_orders.id_customer = ps_vd_customer_dogs.id_customer
    LEFT JOIN ps_order_cart_rule
    ON ps_orders.id_order = ps_order_cart_rule.id_order
    LEFT JOIN ps_message
    ON ps_orders.id_customer = ps_message.id_customer
ORDER BY ps_orders.id_order DESC

这是我的查询。如果我将它缩短并减少到前4个左连接，我会在10分钟内得到结果，但是当我添加其他连接时，我必须等待3个多小时。

我该如何改进？我的目标是创建一个包含我正在选择的所有数据的CSV，以便我们可以改善我办公室中许多人的工作，他们必须在PrestaShop后台检查每个客户的许多参数。
