## ALTER-SYSTEM-ADD-BACKEND
### Name
ALTER SYSTEM ADD BACKEND
### Description
This statement is used to manipulate nodes within a system. (Administrator only!)
grammar:
```sql
-- Add nodes (add this method if you do not use the multi-tenancy function)
ALTER SYSTEM ADD BACKEND "host:heartbeat_port"[,"host:heartbeat_port"...];
-- Add idle nodes (that is, add BACKEND that does not belong to any cluster)
ALTER SYSTEM ADD FREE BACKEND "host:heartbeat_port"[,"host:heartbeat_port"...];
-- Add nodes to a cluster
ALTER SYSTEM ADD BACKEND TO cluster_name "host:heartbeat_port"[,"host:heartbeat_port"...];
````
illustrate:
1. host can be a hostname or an ip address
2. heartbeat_port is the heartbeat port of the node
3. Adding and deleting nodes is a synchronous operation. These two operations do not consider the existing data on the node, and the node is directly deleted from the metadata, please use it with caution.
### Example
1. Add a node
```sql
ALTER SYSTEM ADD BACKEND "host:port";
````
1. Add an idle node
```sql
ALTER SYSTEM ADD FREE BACKEND "host:port";
````
### Keywords
ALTER, SYSTEM, ADD, BACKEND

## ALTER-SYSTEM-ADD-BACKEND
### Name
ALTER SYSTEM ADD BACKEND
### Description
该语句用于操作一个系统内的节点。（仅管理员使用！）
语法：
```sql
1) 增加节点(不使用多租户功能则按照此方法添加)
ALTER SYSTEM ADD BACKEND "host:heartbeat_port"[,"host:heartbeat_port"...];
2) 增加空闲节点(即添加不属于任何cluster的BACKEND)
ALTER SYSTEM ADD FREE BACKEND "host:heartbeat_port"[,"host:heartbeat_port"...];
3) 增加节点到某个cluster
ALTER SYSTEM ADD BACKEND TO cluster_name "host:heartbeat_port"[,"host:heartbeat_port"...];
```
说明：
1. host 可以是主机名或者ip地址
2. heartbeat_port 为该节点的心跳端口
3. 增加和删除节点为同步操作。这两种操作不考虑节点上已有的数据，节点直接从元数据中删除，请谨慎使用。
### Example
1. 增加一个节点
```sql
ALTER SYSTEM ADD BACKEND "host:port";
```
1. 增加一个空闲节点
```sql
ALTER SYSTEM ADD FREE BACKEND "host:port";
```
