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.

Claims

1. 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 data platform configured to supply data to a query associated with an application in a stateless environment; and

a retrieval limitation component configured to

make a preliminary determination regarding whether to continue receiving information for the application, the preliminary determination made as the information is received,

limit a retrieval of the information for the application based on the preliminary determination so as to reduce a total amount of data transferred at any given portion of the query, and

supply at least one identifier option to facilitate a subsequent retrieval of additional data.

2. The computer-implemented system of claim 1, the retrieval limitation component being configured to process the at least one identifier option.

3. The computer-implemented system of claim 1, the stateless environment including a web farm.

4. The computer-implemented system of claim 1, the data platform being configured to supply the data as at least one of a virtual list or paged data.

5. The computer-implemented system of claim 1, the data platform further comprising a query processor.

6. The computer-implemented system of claim 5, further comprising a protocol interpretation component configured to interpret a protocol associated with the data platform.

7. The computer-implemented system of claim 6, the protocol interpretation component comprising an analysis component configured to analyze information associated with a header associated with a query.

8. The computer-implemented system of claim 7, further comprising an application program interface configured to interact with the retrieval limitation component.

9. The computer-implemented system of claim 8, the application program interface comprising an interpreter component configured to determine a type of request by the application.

10. The computer-implemented system of claim 8, further comprising an authorization component configured to determine a privilege associated with access to the data.

11. The computer-implemented system of claim 6, the protocol interpretation component being further configured to extract a compression method from a data header of the request.

12. The computer-implemented system of claim 11, further comprising an artificial intelligence component configured to facilitate data retrieval.
