Calculation engine and calculation providers

摘要

A method of acquiring data and performing calculations on the data using a provider service. A provider ticket service (PTS) receives tickets from one or more clients. Each ticket includes a calculation identifier and a payload. The calculation identifier identifies a calculation to be performed using information in the payload. The PTS associates a unique ticket identifier with each ticket. A ticket manager submits a selected ticket from the PTS to a provider host service (PHS), which determines which provider is to perform the calculation identified by the selected ticket by inspecting provider identification information in the selected ticket. The PHS launches a provider host thread (PHT) that invokes the provider determined to perform the calculation identified by the calculation identifier of the selected ticket. The provider performs the calculation and returns its result to the PHS, which passes the result back to the PTS, which returns the result to the requesting client.
