这个问题是这样的:
- 我们现有的机制只保证了 grpc 请求的可靠性,grpc 请求在,core 除非 kill -9, 否则正常退出是不会导致 leak
- lambda 在 background run 的时候 grpc 请求已经没得了
- 这时候 someone 更新 core,通过 core 保证 background workload recycle 和 expire recycle 失效
- 这个 lambda 容器就永久存在了
解决方案的话我能想到的是:
- 每个 core 在退出的时候通过 hostname 作为 path 记录一个状态到 store 里面
- 这个 host 上的 core 启动的时候自检,load 状态做对应处理,然后删除状态
- 每个请求进来的时候记录一个状态,请求结束的时候清理,同样也需要在 core 启动的时候进行自检
