### 2.6 Failed to call external grpc service
1. `RC` depends on `DC` and `IC`, if the grpc call failed, it needs to reconnect.
2. `RC` does not listen to the status of the `DC` and `IC` in real time.
1. `RootCoord` depends on `DataCoord` and `IndexCoord`, if the grpc call failed, it needs to reconnect.
2. `RootCoord` does not listen to the status of the `DataCoord` and `IndexCoord` in real time.
### 2.7 Add virtual channel assignment when creating a collection
1. Add a new field, "number of shards" in the `create collection` request. The "num of shards" tells the `RC` to create the number of virtual channels for this collection.
1. Add a new field, "number of shards" in the `create collection` request. The "num of shards" tells the `RootCoord` to create the number of virtual channels for this collection.
2. In the current implementation, virtual channels and physical channels have a one-to-one relationship, and the total number of physical channels increases as the number of virtual channels increases; later, the total number of physical channels needs to be fixed, and multiple virtual channels share one physical channel.
3. The name of the virtual channel is globally unique, and the `collection meta` records the correspondence between the virtual channel and the physical channel.
