+/**
+ * An annotation used to prefetch changed data for
+ * {@link org.apache.helix.zookeeper.zkclient.IZkDataListener} in ZkClient.
+ * <p>
+ * Example:
+ * <pre>
+ * {@code @PreFetch(enabled = false)}
+ * public class MyCallback implements IZkDataListener
+ * </pre>
+ * {@code @PreFetch(enabled = false)} means data will not be prefetched in
ZkClient before
