Systems and methods are described for optimizing logging of decision outcomes in distributed transaction protocols. An example method may comprise: executing, by a processing device, a transaction manager to coordinate a distributed transaction for a plurality of participants; transmitting, by the processing device via the transaction manager, prepare messages to the plurality of participants; serializing a transaction log record of the distributed transaction in parallel with the transmitting of the prepare messages; speculatively writing the serialized transaction log record in persistent memory while the transaction manager performs the serializing of the transaction log record; and updating a speculative indicator associated with the distributed transaction to indicate validity of the transaction log record.

Optimizing logging of decision outcomes in distributed transactions

Systems and methods are described for optimizing logging of decision outcomes in distributed transaction protocols. An example method may comprise: executing, by a processing device, a transaction manager to coordinate a distributed transaction for a plurality of participants, transmitting, by the processing device via the transaction manager, prepare messages to the plurality of participants, and while waiting to receive responses from each of the plurality of participants, serializing a transaction log record of the distributed transaction.

Systems and methods are provided for enlisting single phase commit resources in a two phase commit transaction. An exemplary method includes accessing a global transaction having a plurality of processes requiring single phase commit (1PC) resource and a two phase commit (2PC) resource, initializing a 1PC resource manager for the 1PC resource with a first process of the plurality of processes, wherein the first process requires the 1PC resource, preparing a 2PC resource manager for the 2PC resource with a second process of the plurality of processes, wherein the second process requires the 2PC resource, generating a unique identifier for the 1PC resource, transmitting the unique identifier to the 1PC resource manager, and instructing the 1PC resource manager to commit the first process to the 1PC resource, wherein committing the first process to the 1PC resource comprises recording the unique identifier to the 1PC resource.
