# Sentinel DataSource Consul
Sentinel DataSource Consul provides integration with Consul. The data source leverages blocking query (backed by
long polling) of Consul.
## Usage
To use Sentinel DataSource Consul, you could add the following dependency:
```xml
com.alibaba.csp
sentinel-datasource-consul
x.y.z
```
Then you can create a `ConsulDataSource` and register to rule managers.
For instance:
```java
ReadableDataSource> dataSource = new ConsulDataSource<>(host, port, ruleKey, waitTimeoutInSecond, flowConfigParser);
FlowRuleManager.register2Property(dataSource.getProperty());
```
- `ruleKey`: the rule persistence key
- `waitTimeoutInSecond`: long polling timeout (in second) of the Consul API client
