-- Migration: 125_add_channel_monitors
|
|
-- 渠道监控 MVP：周期性对外部 provider/endpoint/api_key 做模型心跳测试。
|
|
--
|
|
-- 表结构说明：
|
|
-- - channel_monitors 渠道配置表（一行 = 一个监控对象）
|
|
-- - channel_monitor_histories 检测历史明细表（一次检测一个模型 = 一行）
|
|
--
|
|
-- 设计要点：
|
|
-- - api_key_encrypted 列存放 AES-256-GCM 密文（base64），由 service 层加密。
|
|
-- - extra_models 用 JSONB 存储字符串数组，便于扩展（后续可加权重等元数据）。
|
|
-- - history 表通过 ON DELETE CASCADE 自动清理已删除监控的历史。
|
|
-- - (enabled, last_checked_at) 索引服务于调度器扫描“到期需要检测”的监控。
|
|
-- - histories 上 (monitor_id, model, checked_at DESC) 服务用户视图聚合查询；
|
|
-- 单独的 (checked_at) 索引服务定期清理 30 天前数据的 DELETE。
