Abstract

Techniques are described for generating transaction data for a transaction, the transaction data generated with varying fidelity levels based on various constraints. In response to a transaction request from a client, a contract engine may perform service call(s) that instruct network service(s) to generate transaction data. The service call(s) may include constraint(s) on the generation of the transaction data, such as a time limit or a requested fidelity. The network service(s) may generate the transaction data at a particular fidelity based on the time limit, requested fidelity, or other criteria such as current load on the network service(s). The transaction data may be communicated to the contract engine with a fidelity indicator. Lower fidelity transaction data may be sent to the client to enable a low latency user experience. The lower fidelity transaction data may subsequently be replaced with higher fidelity transaction data generated with higher latency.

Dependent claims

A method, comprising:

performing, by one or more computers:
accessing, by a backend service, a transaction request from a client process, the transaction request describing a transaction;
performing, by the backend service responsive to the transaction request, a plurality of respective service calls over a network to instruct different respective ones of a plurality of distinct network services to generate transaction data to be combined into an aggregate data object for responding to the transaction request, wherein different service calls of the plurality of respective service calls over the network to the respective network services of the plurality of network services include one or more respective constraints on a time to provide the transaction data or on fidelity for which the respective network service is to provide the transaction data, and wherein the fidelity indicates an accuracy of the transaction data, or a degree of variance of a calculated portion of the transaction data relative to a highest fidelity version of the calculated portion of the transaction data, or a quality of the transaction data, and wherein the constraints are different for different transaction requests;
generating transaction data at a determined fidelity, by a given network service of the respective network services in response to one of the respective service calls, wherein said generating comprises:
accessing historical data of previously measured generation times for other instances of the requested transaction data or similar transaction data that were generated;
and
determining the fidelity based on the one or more respective constraints included in the service call to the respective network service and based on the historical data;
accessing, by the backend service, data objects generated by the respective network services in response to the respective service calls, the individual ones of the data objects including:
the respective transaction data that is generated, by the respective network service, at a highest fidelity that the respective service determined possible according to the one or more respective constraints included in the respective service call to the respective network service, wherein the fidelity of the generated transaction data is different for service calls corresponding to different transaction requests in accordance with the different one or more constraints for the respective transaction request;
and
a respective fidelity indicator indicating the fidelity of the respective transaction data generated by the respective network service;
combining, by the backend service, the respective transaction data from the respective data objects generated by the respective network services in the aggregate data object;
and
providing the aggregate data object to the client process.
