# Sentinel DataSource ZooKeeper
|
||
|
|
|
||
|
|
Sentinel DataSource ZooKeeper provides integration with ZooKeeper so that ZooKeeper
|
||
|
|
can be the dynamic rule data source of Sentinel. The data source uses push model (listener).
|
||
|
|
|
||
|
|
To use Sentinel DataSource ZooKeeper, you should add the following dependency:
|
||
|
|
|
||
|
|
```xml
|
||
|
|
<dependency>
|
||
|
|
<groupId>com.alibaba.csp</groupId>
|
||
|
|
<artifactId>sentinel-datasource-zookeeper</artifactId>
|
||
|
|
<version>x.y.z</version>
|
||
|
|
</dependency>
|
||
|
|
```
|
||
|
|
|
||
|
|
Then you can create an `ZookeeperDataSource` and register to rule managers.
|
||
|
|
For instance:
|
||
|
|
|
||
|
|
```java
|
||
|
|
// `path` is the data path in ZooKeeper
|
||
|
|
ReadableDataSource<String, List<FlowRule>> flowRuleDataSource = new ZookeeperDataSource<>(remoteAddress, path, source -> JSON.parseObject(source, new TypeReference<List<FlowRule>>() {}));
|
||
|
|
FlowRuleManager.register2Property(flowRuleDataSource.getProperty());
|
||
|
|
```
|
||
|
|
|
||
|
|
> Note: It's not recommended to add a large amount of rules to a single path (has limitation, also leads to bad performance).
|
||
|
|
|
||
|
|
We've also provided an example: [sentinel-demo-zookeeper-datasource](https://github.com/alibaba/Sentinel/tree/master/sentinel-demo/sentinel-demo-zookeeper-datasource).
