Detecting and addressing clashing transactions in a service-based architecture

Abstract

A method of processing service requests in a service-based network architecture comprising a plurality of service instances includes receiving, at a service, a service request from a sender, the service request including a user identification, ID, associated with the request and a transaction ID associated with the request, obtaining a user context associated with the user ID from a user context database, the user context including a user context version and a transaction ongoing flag, determining based on the transaction ongoing flag whether a transaction involving the user ID is currently ongoing, in response to determining that a transaction involving the user ID is not currently ongoing, processing the service request to obtain an updated key value, and transmitting a store request to the user context database to store the updated key value, and an updated user context version in the user context database.
