Data streaming for interactive decision-oriented software applications

摘要

Providing data to a computer software application by intercepting a request made by a computer software application to retrieve a first data set from a first data storage location, accessing a record, defined in advance of the request, that includes a reference to the first data set and a reference to a second data set, retrieving the first data set from a data storage location other than the first data storage location, and retrieving the second data set from a data storage location other than the first data storage location in advance of a request by the computer software application to access the second data set at the first data storage location.

主权项

1. A method for evaluating candidate data retrieval plans, the method comprising:
a) traversing a log to identify within the log requests for data made by a computer software application, wherein the log was compiled during an execution of the computer software application to record the requests for data, and wherein the traversing is performed at a time other than during execution of the computer software application; b) retrieving data responsive to any of the requests for data identified within the log, wherein the retrieving is performed in accordance with a data retrieval plan that is associated with the data that are the subject of the request for data, and wherein the retrieving is performed at a time other than during execution of the computer software application; and c) determining a total delay associated with the data retrieval plan based on processing delays stored in the log and delays associated with retrieving the data.
