Methods and systems are provided for client controlled transaction processing. The method may be carried out at a transaction server, and include: receiving a transaction request from a transaction initiator and allocating a transaction identifier to the transaction; receiving notification of the number of jobs to be completed in the transaction; maintaining a transaction status indicating the current status of the transaction; receiving job status updates from one or more participants processing the jobs included in the transaction and updating a transaction record reflecting the status of each of the jobs included in the transaction; updating the transaction status when required based on the job status updates of the jobs included in the transaction; and receiving and responding to transaction status polling to provide a current transaction status, where the transaction status polling originates from the transaction initiator and the participants processing the jobs.

Client controlled transaction processing involving a plurality of participants

A facility for event failure management is provided, which includes providing a failed event database containing failed event information relating to failed events and one or more components associated with each of the failed events. Upon modification to a component associated with a failed event, the failed event is retried. Based on a result of retrying the failed event, failed event information of the failed event database is updated. The failed event database may therefore be dynamically and/or automatically updated so that it contains up-to-date and appropriate information for predicting and/or managing event failures.

A method for configuring an adaptable circuit breaker chain in a microservices architecture includes transmitting a request from an upstream service to a target one of the services and receiving in a circuit breaker of the upstream service a response from a circuit breaker of the target indicating an inability to provide a response to the transmitted request and including meta-data describing an attempt by the circuit breaker of the target to receive a response from the downstream service to an underlying request of the target necessary to provide a response to the request transmitted by the upstream service. Finally, on condition that the meta-data indicates a delay by the circuit breaker of the target incurred in receiving a response to the underlying request, the method includes changing a pattern of delay imposed by the circuit breaker of the upstream service from a default pattern of delay.
