TiKV JAVA Client

A Java client for TiDB/TiKV. It is supposed to:

• Communicate via gRPC
• Talk to Placement Driver searching for a region
• Talk to TiKV for reading/writing data and the resulted data is encoded/decoded just like what we do in TiDB.
• Talk to Coprocessor for calculation pushdown

Quick Start

TiKV Java Client is designed to communicate with pd and tikv, please run TiKV and PD in advance.

Build java client from source file:

mvn clean install -Dmaven.test.skip=true

Add maven dependency to pom.xml:

<dependency>
	<groupId>org.tikv</groupId>
	<artifactId>tikv-client-java</artifactId>
	<version>3.1.0</version>
</dependency>

Create a RawKVClient and communicates with TiKV:

import org.tikv.common.TiConfiguration;
import org.tikv.common.TiSession;
import org.tikv.raw.RawKVClient;

public class Main {
	public static void main() {
		// You MUST create a raw configuration if you are using RawKVClient.
		TiConfiguration conf = TiConfiguration.createRawDefault(YOUR_PD_ADDRESSES);
		TiSession session = TiSession.create(conf);
		RawKVClient client = session.createRawClient();
	}
}
