Abstract
Methods, systems, apparatuses, and computer program products are provided for coordinating a distributed database transaction. A transaction driver, such as a client machine, may initiate a distributed transaction. The transaction driver may transmit to a transaction coordinator a driver report that includes identifying information related to the distributed transaction, including an identification of participants involved in the transaction. The coordinator may determine whether participant reports, which include a status of the portion of the distributed database transaction of a particular participant, are received from each of the participants. Participant reports may also identify participants that are descendants of the reporting participant. The transaction coordinator may store, in a table, information to track the progress of the distributed transaction. Using the table, an outcome of the distributed transaction may be determined and transmitted to one or more of the involved participants.
