Retrieving data using an asynchronous buffer

A machine-readable medium when executed by a processor, causes the processor to

• perform a method for processing messages, the method comprising:
• 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.

A data processing system, comprising:

• a processor;
• and
• a memory coupled to the processor for storing instructions, when executed from the memory, causes the processor to
• in response to a request for first data from a client via a first thread, determine 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,
• generate 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
• return the first thread to the client while waiting for a result of the second thread from the server.
