@InterfaceAudience.Public
public interface AsyncCallback

Interface definitions of asynchronous callbacks. An asynchronous callback is deferred to invoke after a function returns. Asynchronous calls usually improve system efficiency on IO-related APIs.

ZooKeeper provides asynchronous version as equivalent to synchronous APIs.
