What is the process for put and get operations when using tikv-client-java 3.1.0 to interact with a TiKV cluster, and how can batchGet be optimized for better performance? Are there any relevant documents available for reference?

// Configure TiKV session
TiConfiguration conf = TiConfiguration.createDefault();
TiSession session = TiSession.create(conf);

try {
    // Put data
    byte[] keyBytes = "myKey".getBytes();
    byte[] valueBytes = "myValue".getBytes();
    Key key = TypedKey.from(keyBytes);
    session.getKVClient().put(key, valueBytes);

    // Get data
    byte[] retrievedValue = session.getKVClient().get(key);

    if (retrievedValue != null) {
        System.out.println("Retrieved value: " + new String(retrievedValue));
    } else {
        System.out.println("Key not found.");
    }
} catch (TiClientInternalException e) {
    e.printStackTrace();
} finally {
    session.close();
}

This response is a bit lengthy, so I’ll explain the middle part as I understand it.
For the batchGet operation, TiKV provides a way to read multiple keys in bulk to improve read performance. In the batchGet operation, the client can send multiple keys to TiKV at once, and then TiKV reads the corresponding data from the replicas of various Regions in parallel and returns the results to the client.
