Caching is one of the best ways to improve API performance. If you have requests that frequently produce the same response, a cached version of the response avoids excessive database queries. The easiest way to cache responses is to periodically expire it, or force it to expire when certain data updates happen.

What is not advantage of statelessness in RESTful web services?

This restriction is called Statelessness. Each request from the client to server must contain all of the information necessary to understand the request, and cannot take advantage of any stored context on the server. Session state is therefore kept entirely on the client.

What are RESTful services?

RESTful Web Services are basically REST Architecture based Web Services. In REST Architecture everything is a resource. RESTful web services are light weight, highly scalable and maintainable and are very commonly used to create APIs for web-based applications.
