Abstract: A database-native Lock-Free Reservation infrastructure is used to provide automatic compensation for the reservable column updates made by successful local transactions (or microservice actions) that are part of a saga that is being aborted. The automatic compensation is achieved by tracking the reservable column updates in a reservations journal, within the database, during the execution of the local transaction and remembering them beyond the commit of the local transaction until the finalization of the saga that the transaction is a part of. If the saga aborts, then the database server automatically uses the information retained in the reservations journal to compensate for the changes made by the committed transactions that were part of the saga.

Abstract: A controller of a processor core may select telemetry data generated by a plurality of sensors of the processor core at a first time interval of a plurality of time intervals. The controller may transform the telemetry data based at least in part on a model. The controller may detect a change at the first time interval based on the transformed telemetry data. The controller may determine an event based on the change. The controller may initiate an action during the first time interval based on the event.
