# 示例代码：设置推送间隔
import time

def send_promotion(user_id, message):
    last_sent_time = get_last_sent_time(user_id)  # 获取上次推送时间
    current_time = time.time()
    if current_time - last_sent_time > 3600:  # 至少间隔1小时
        push_message(user_id, message)
        update_last_sent_time(user_id, current_time)  # 更新推送时间

# 示例代码：基于用户行为的推送优化
def optimize_push_content(user_id):
    user_preferences = get_user_preferences(user_id)
    if user_preferences['preferred_category'] == 'electronics':
        message = "Electronics sale! Up to 50% off."
    else:
        message = "General sale! Various discounts available."
    send_promotion(user_id, message)

# 示例代码：使用负载均衡
from load_balancer import LoadBalancer

lb = LoadBalancer()
def send_promotion_with_lb(user_id, message):
    lb.send_request(user_id, message)
