Data paging with a stateless service

Abstract

Systems and methods that facilitate data retrieval in a stateless environment by limiting amount of retrievable data associated with a single client request. A retrieval limitation component partially satisfies a query and retrieves an initial batch of information. Moreover, identifications can further be designated to retrieve additional information if so is required. Accordingly, an application requesting data thru a query can initially be supplied with a limited number of data, which subsequently can be followed by additional data items returned as unique identifiers.

What is claimed is: 
     
         1 . A method of retrieving data comprising:
 partially satisfying a query submitted by an application as part of a data platform in a stateless environment;   limiting a retrieval of information for the query based on a preliminary determination regarding whether to continue receiving information for the application, the preliminary determination made as the information is received; and   supplying additional information for the query as unique identifiers.   
     
     
         2 . The method of  claim 1  further comprising retrieving an initial batch of data from the data platform, in response to a single query by the application. 
     
     
         3 . The method of  claim 2  further comprising explicitly requesting a number of full data items in response to the single query. 
     
     
         4 . The method of  claim 3  further comprising retrieving data without a requirement to progress through data linearly. 
     
     
         5 . The method of  claim 3  further comprising retrieving predetermined ranges of data for the query. 
     
     
         6 . The method of  claim 3  further comprising automatically load balancing between web servers associated with the stateless environment. 
     
     
         7 . The method of  claim 3  further comprising crafting user experiences in form of list views. 
     
     
         8 . A computer-readable storage medium, comprising:
 a memory component configured to store computer-readable instructions, the computer-readable instructions including instructions for performing the following acts:   partially executing a query received from an application as part of a data platform in a stateless environment;   performing a preliminary determination regarding whether to continue receiving information for the application, the preliminary determination made as the information is received; and   limiting a retrieval of information for the query based on the preliminary determination.   
     
     
         9 . The computer-readable storage medium of  claim 8 , the acts further comprising supplying additional information for the query as unique identifiers. 
     
     
         10 . The computer-readable storage medium of  claim 8 , the acts further comprising retrieving an initial batch of data from the data platform. 
     
     
         11 . The computer-readable storage medium of  claim 10 , the acts further comprising requesting a number of full data items. 
     
     
         12 . The computer-readable storage medium of  claim 11 , the acts further comprising retrieving data without a requirement to progress through data linearly. 
     
     
         13 . The computer-readable storage medium of  claim 11 , the acts further comprising retrieving predetermined ranges of data for the query. 
     
     
         14 . The computer-readable storage medium of  claim 11 , the acts further comprising load balancing between web servers associated with the stateless environment. 
     
     
         15 . The computer-readable storage medium of  claim 11 , the acts further comprising crafting user experiences in form of list views. 
     
     
         16 . A computer-implemented system comprising at least one processor coupled to at least one machine-readable storage medium storing instructions executable by the at least one processor to implement:
 a retrieval limitation component configured to limit a retrieval of information for an application based on a preliminary determination regarding whether to continue receiving information for the application, the preliminary determination made as the information is received; and   an option component configured to provide an option to facilitate a subsequent retrieval of additional data.   
     
     
         17 . The computer-implemented system of  claim 16 , the retrieval limitation component configured to receive the information from a data platform configured to supply data to a query associated with the application in a stateless environment. 
     
     
         18 . The computer-implemented system of  claim 17 , the stateless environment including a web farm. 
     
     
         19 . The computer-implemented system of  claim 17 , the data platform configured to supply the data as at least one of a virtual list or paged data. 
     
     
         20 . The computer-implemented system of  claim 17 , the data platform further comprising a query processor.
