## 进入容器功能 用户进行gdb ,pstack ## 查看gc_dir 通过http or 用户跳到宿主机查看

### 背景 目前在galaxy 调度器 采用FCFS(First come ，First served)策略，当chunkserver，tabletserver 出现故障或者升级时释放出资源，此时上层计算任务先到达调度器，可用占用释放出的资源，而后到的chunkserver,tabletserver无法重新部署到以前的机器上面，会导致chunkserver丢副本，tabletserver丢ssd cache ### 优先级分类 对galaxy服务的应用可以大致抽象3个优先级层次出来 - 对硬件资源有需要的chunkserver,tabletserver storage_service 100 - 常驻内存只对cpu 内存有需求的 normal_service 70 - 只运行一段时间的 batch_task 20 ### 抢占策略 采用悲观抢占方式，每次抢占都要全局最优，同一类优先级服务不抢占，只抢占下一层级资源，但享受优先调度, ###...

从性能上来看[flatbuffer benchmark](https://google.github.io/flatbuffers/flatbuffers_benchmarks.html), flatbuffer比protobuf的优势还是有的，而[grpc对flatbuffer支持](https://github.com/grpc/grpc/issues/5438)也在计划中。

Description: When running cargo-prove prove build and Cargo.toml is not found in the current directory or any parent directory, the current error message is: ``` thread 'main' panicked at cli/src/build.rs:27:40:...
