Abstract
A mechanism for retrieving data over a network using an asynchronous buffer is described herein. According to one embodiment, an exemplary process includes, in response to a request for first data from a client via a first thread, determining whether a local circular buffer contains the requested first data, the local circular buffer having a head region and a tail region for identifying a head and a tail of the local circular buffer respectively, and the local circular buffer containing a portion of a data file maintained by a server over a network, generating a second thread to the server over the network to request the first data, if the local circular buffer does not contain the requested first data, and returning the first thread to the client while waiting for a result of the second thread from the server. Other methods and apparatuses are also described.
