实现功能: - 实名状态检查轮询(可配置间隔) - 卡流量检查轮询(支持跨月流量追踪) - 套餐检查与超额自动停机 - 分布式并发控制(Redis 信号量) - 手动触发轮询(单卡/批量/条件筛选) - 数据清理配置与执行 - 告警规则与历史记录 - 实时监控统计(队列/性能/并发) 性能优化: - Redis 缓存卡信息,减少 DB 查询 - Pipeline 批量写入 Redis - 异步流量记录写入 - 渐进式初始化(10万卡/批) 压测工具(scripts/benchmark/): - Mock Gateway 模拟上游服务 - 测试卡生成器 - 配置初始化脚本 - 实时监控脚本 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
