## TiKV JAVA Client
A Java client for [TiKV](https://github.com/tikv/tikv).
It is supposed to:
+ Communicate via [gRPC](http://www.grpc.io/)
+ Talk to Placement Driver searching for a region
+ Talk to TiKV for reading/writing data
## Quick Start
> TiKV Java Client is designed to communicate with [PD](https://github.com/tikv/pd) and [TiKV](https://github.com/tikv/tikv), please run PD and TiKV in advance.
Build Java client from source file:
```sh
mvn clean install -Dmaven.test.skip=true
```
Add maven dependency to `pom.xml`:
```xml
<dependency>
<groupId>org.tikv</groupId>
<artifactId>tikv-client-java</artifactId>
<version>3.3.0</version>
</dependency>
```
Create a transactional `KVClient` and communicates with TiKV:
```java
import org.tikv.common.TiConfiguration;
import org.tikv.common.TiSession;
import org.tikv.txn.KVClient;
public class Main {
public static void main(String[] args) throws Exception {
TiConfiguration conf = TiConfiguration.createDefault(YOUR_PD_ADDRESSES);
TiSession session = TiSession.create(conf);
KVClient client = session.createKVClient();
}
}
```
Or create a `RawKVClient` if you don't need the transaction semantic:
```java
import org.tikv.common.TiConfiguration;
import org.tikv.common.TiSession;
import org.tikv.raw.RawKVClient;
public class Main {
public static void main(String[] args) throws Exception {
TiConfiguration conf = TiConfiguration.createRawDefault(YOUR_PD_ADDRESSES);
TiSession session = TiSession.create(conf);
RawKVClient client = session.createRawClient();
}
}
```
