Abstract

Techniques are described for parallel processing of items, specified for purchase in a transaction. A transaction request may be received, specifying a plurality of items in a transaction. Multiple subsets of one or more items may be determined that are suitable for parallel processing by multiple instances of a network services, the subsets determined based on configuration information describing a parallel processing capability of the network service specified during registration. Multiple service calls may be made to cause the multiple instances of the network service to generate transaction data corresponding to the subsets. The transaction data may be incorporated into an aggregate contract data object on receipt, and provided to client process(es) for presentation via a user interface such as an e-commerce application.

Claims20

Dependent claims

A method comprising:

accessing a transaction request describing a transaction to purchase a plurality of items, the transaction request entered through an e-commerce application;
initializing an aggregate contract data object to store transaction data regarding the transaction;
identifying a plurality of network services that are executable by one or more computing devices, the plurality of network services configured to operate independently of one another to generate a plurality of data objects to include in the aggregate contract data object;
accessing configuration information for a network service of the plurality of network services, the configuration information describing a parallel processing capability of the network service;
based at least partly on the configuration information, determining at least two subsets of the plurality of items, the at least two subsets comprising non-overlapping subsets;
performing at least two calls to cause at least two instances of the network service to execute in parallel to generate at least two data objects, each of the at least two data objects including at least a portion of the transaction data corresponding to one of the at least two subsets of the plurality of items;
and
incorporating the at least two data objects into the aggregate contract data object.

5 more elements

A system, comprising:

one or more computing devices comprising one or more hardware processors and memory and configured to provide one or more services, the one or more services configured to:
access a transaction request describing a transaction associated with a plurality of items;
identify a plurality of network services that are configured to operate independently of one another to generate a plurality of data objects to include in an aggregate data object;
determine at least two subsets of the plurality of items, the at least two subsets comprising non-overlapping subsets;
perform at least two calls to at least two instances of a network service of the plurality of network services, wherein the at least two calls cause the at least two instances of the network service to execute in parallel to generate at least two data objects, each of the at least two data objects including at least a portion of the transaction data corresponding to one of the at least two subsets of the plurality of items;
and
incorporate, into the aggregate data object, the transaction data included in the at least two data objects.

4 more elements

One or more non-transitory computer-readable media storing instructions which, when executed by one or more processors, instruct the one or more processors to perform actions comprising:

accessing a transaction request describing a transaction associated with a plurality of items;
determining at least two subsets of the plurality of items;
performing at least two calls to at least two instances of a network service, wherein the at least two calls cause the at least two instances of the network service to execute in parallel to generate at least two data objects, each of the at least two data objects including at least a portion of the transaction data corresponding to one of the at least two subsets of the plurality of items;
and
incorporating, into an aggregate data object, the transaction data included in the at least two data objects.
