Abstract
Systems and methods are provided for prepare list communication to participants in a two-phase commit protocol transaction processing. An exemplary method includes receiving a distributed transaction for processing, wherein the processing uses a two-phase commit protocol, preparing a first participating node comprising a first process of the distributed transaction, and preparing a second participating node comprising a second process of the distributed transaction. The method further includes determining whether the first participating node can commit the first process and transmitting the determination the first participating node can commit the first process to the second participating node. The first participating node and the second participating node may determine a coordinator of the distributed transaction has failed and the second participating node may use the determination to query the first participating node for a transaction outcome, such as a commit of fail state.
