Abstract

Systems and methods are provided for semi-synchronously exporting data. A web server creates an export record in response to receiving a data request from a client computer. The web server sends a token to the client computer, wherein receipt of the token enables the client computer to be used for other purposes while waiting for receipt of requested data. At least one of multiple batch processing servers processes the data request in response to accessing the export record. At least one of the multiple batch processing servers updates the export record to reflect the processing of the data request. The web server exports the processed data request to the client computer in response to identifying an update of the export record.

Claims

1. An apparatus for semi-synchronously exporting data, the apparatus comprising:

a processor; and

one or more stored sequences of instructions which, when executed by the processor, cause the processor to carry out the steps of;

creating, by a web server, an export record in response to receiving a data request from a client computer;

sending, by the web server, a token to the client computer, wherein receipt of the token enables the client computer to be used for other purposes while waiting for receipt of requested data;

processing, by at least one of a plurality of batch processing servers, the data request in response to accessing the export record;

updating, by the at least one of the plurality of batch processing servers, the export record to reflect the processing of the data request; and

exporting, by the web server, the processed data request to the client computer in response to identifying an update of the export record.

2. The apparatus of claim 1, wherein the steps further comprise:

determining, by the web server, whether an account associated with the client computer has sufficient credit for receiving the requested data, prior to creating the export record, in response to receiving the data request from the client computer; and

sending, by the web server, options to the client computer in response to a determination that the account does not have sufficient credit for receiving the requested data, wherein the options comprise adding all of the requested data to a cart for later use, using available credit to purchase a portion of the requested data, and modifying the data request.

3. The apparatus of claim 1, wherein the steps further comprise synchronously exporting, by the web server, a portion of the requested data until an export of the portion of the requested data reaches a threshold in response to receiving the data request from the client computer, wherein a remainder of the requested data is asynchronously exported.

4. The apparatus of claim 1, wherein the client computer uses the token to poll the web server to determine when the data request has been processed.

5. The apparatus of claim 1, wherein the steps further comprise notifying, by the web server, the client computer that the data request has been processed.

6. A machine-readable medium carrying one or more sequences of instructions for semi-synchronously exporting data, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:

creating, by a web server, an export record in response to receiving a data request from a client computer;

sending, by the web server, a token to the client computer, wherein receipt of the token enables the client computer to be used for other purposes while waiting for receipt of requested data;

processing, by at least one of a plurality of batch processing servers, the data request in response to accessing the export record;

updating, by the at least one of the plurality of batch processing servers, the export record to reflect the processing of the data request; and

exporting, by the web server, the processed data request to the client computer in response to identifying an update of the export record.

7. The machine-readable medium of claim 6, wherein the steps further comprise:

determining, by the web server, whether an account associated with the client computer has sufficient credit for receiving the requested data, prior to creating the export record, in response to receiving the data request from the client computer; and

sending, by the web server, options to the client computer in response to a determination that the account does not have sufficient credit for receiving the requested data, wherein the options comprise adding all of the requested data to a cart for later use, using available credit to purchase a portion of the requested data, and modifying the data request.

8. The machine-readable medium of claim 6, wherein the steps further comprise synchronously exporting, by the web server, a portion of the requested data until an export of the portion of the requested data reaches a threshold in response to receiving the data request from the client computer, wherein a remainder of the requested data is asynchronously exported.

9. The machine-readable medium of claim 6, wherein the client computer uses the token to poll the web server to determine when the data request has been processed.

10. The machine-readable medium of claim 6, wherein the steps further comprise notifying, by the web server, the client computer that the data request has been processed.

11. A method for semi-synchronously exporting data, the method comprising:

creating, by a web server, an export record in response to receiving a data request from a client computer;

sending, by the web server, a token to the client computer, wherein receipt of the token enables the client computer to be used for other purposes while waiting for receipt of requested data;

processing, by at least one of a plurality of batch processing servers, the data request in response to accessing the export record;

updating, by the at least one of the plurality of batch processing servers, the export record to reflect the processing of the data request; and

exporting, by the web server, the processed data request to the client computer in response to identifying an update of the export record.

12. The method of claim 11, further comprising:

determining, by the web server, whether an account associated with the client computer has sufficient credit for receiving the requested data, prior to creating the export record, in response to receiving the data request from the client computer; and

sending, by the web server, options to the client computer in response to a determination that the account does not have sufficient credit for receiving the requested data, wherein the options comprise adding all of the requested data to a cart for later use, using available credit to purchase a portion of the requested data, and modifying the data request.

13. The method of claim 11, further comprising synchronously exporting, by the web server, a portion of the requested data until an export of the portion of the requested data reaches a threshold in response to receiving the data request from the client computer, wherein a remainder of the requested data is asynchronously exported.

14. The method of claim 11, wherein the client computer uses the token to poll the web server to determine when the data request has been processed.

15. The method of claim 11, further comprising notifying, by the web server, the client computer that the data request has been processed.

16. A method for transmitting code for semi-synchronously exporting data on a transmission medium, the method comprising:

transmitting code to create, by a web server, an export record in response to receiving a data request from a client computer;

transmitting code to send, by the web server, a token to the client computer, wherein receipt of the token enables the client computer to be used for other purposes while waiting for receipt of requested data;

transmitting code to process, by at least one of a plurality of batch processing servers, the data request in response to accessing the export record;

transmitting code to update, by the at least one of the plurality of batch processing servers, the export record to reflect the processing of the data request; and

transmitting code to export, by the web server, the processed data request to the client computer in response to identifying an update of the export record.

17. The method for transmitting code of claim 16, further comprising:

transmitting code to determine, by the web server, whether an account associated with the client computer has sufficient credit for receiving the requested data, prior to creating the export record, in response to receiving the data request from the client computer; and
