PREDICTIVE CONCURRENCY CONTROL PROTOCOL AND SYSTEM THEREOF

Abstract: a system and method of the device may include during a validation phase of a transaction, identifying conditional conflicts and their corresponding conflicting transactions, where the corresponding conflicting transactions are reading-transactions conflicting with the transaction. in addition, the device may include for each conditional conflict, classifying its state to determine if the transaction can commit, with respect to the conditional conflict, before the corresponding conflicting transaction. the device may include marking the transaction as dependent on the corresponding conflicting transaction when the transaction cannot commit before the corresponding conflicting transaction. moreover, the device may include placing a commit pause on data cells modified by the transaction, thereby allowing the transaction to commit, when the transaction can commit before any corresponding conflicting transactions.
