Distributed search in a casual network of servers
First Claim
1. A system for providing a distributed casual search, the system comprising an originating server comprising:
- a memory storage; and
a processing unit coupled to the memory storage, wherein the processing unit is operative to;
determine that a first request cannot be fulfilled by information associated with the originating server;
post the first request to a distributed request ring;
receive a response to the first request from a remote server, the response including current data, the remote server having a foreign reference written in response to receiving the first request by the remote server and employed to update the current data on the originating server when;
the current data stored on a data store associated with the remote server is updated,a predicate created by an owner of the current data is satisfied, the predicate determining whether the updated current data is propagated to the originating server;
save, at the originating server, the response to the first request;
receive a second request from a second client; and
determine that the second request can be fulfilled by the saved response to the first request.

Abstract
Distributed searches in a casual server network may be provided. First it may be determined, at an originating server, that a first request cannot be fulfilled by information associated with the originating server. Then, from the originating server, the first request may be posted to a distributed request ring. Next, at a remote server on the distributed request ring, the first request may be received. The remote server may then query for current data on a data store associated with the remote server that may satisfy the first request. The remote server may next write a foreign reference in the data store. The foreign reference may indicate that the originating server requested the current data. Next, at the originating server, a response may be received to the first request from the remote server. The response may include the current data.

8. A computer-readable storage device which stores a set of instructions which when executed performs a method for providing a distributed casual search, the method executed by the set of instructions comprising:
-
receiving, at a remote server on a distributed request ring, a first request; querying, by the remote server, for current data on a data store associated with the remote server that will satisfy the first request; writing in the data store associated with the remote server, a foreign reference indicating that the originating server requested the current data, wherein writing the foreign reference is triggered in response to receiving the query for the current data on the data store associated with the remote server; receiving, at the remote server, a command to update the current data, the command including updated data to replace the current data associated with the remote server; determining, at the remote server, that the foreign reference is associated with the current data; and transmitting, in accordance to the foreign reference, the updated data to the originating server, wherein transmitting, in accordance to the foreign reference, comprises transmitting the updated data when the foreign reference indicates that a predicate for transmission has been satisfied, the predicate being created by an owner of the updated data and indicating whether the updated data is to be propagated to the originating server. - View Dependent Claims (9)

10. A method for providing a distributed casual search, the method comprising:
-
determining that a first request cannot be fulfilled by information associated with an originating server; posting the first request to a distributed request ring; receiving a response to the first request from a remote server, the response including current data, the remote server having a foreign reference written in response to receiving the first request by the remote server and employed to update the current data on the originating server when; the current data stored on a data store associated with the remote server is updated, and a predicate created by an owner of the current data is satisfied, the predicate determining whether the updated current data is propagated to the originating server; saving, at the originating server, the response to the first request; receiving a second request from a second client; and determining that the second request can be fulfilled by the saved response to the first request. - View Dependent Claims (11, 12, 13, 14, 15, 16)
