Methods and systems for distributed transaction processing include assigning portions of a logical unit of work to one or more transaction participants. Resource usage information relating to the portions of the logical unit of work is tracked from the respective one or more transaction participants. A last participant is determined based on the tracked resource usage information using a processor. The logical unit of work is resolved. Resolving the logical unit of work includes sending a prepare flow to each of the transaction participants except the last participant to optimize resolution efficiency.
