linear two-phase commit (L-2pc) protocol is used in the commit processing of distributed transactions via the transaction managers of the various nodes when transaction runs serially. However, it suffers from the poor recovery process and some other associated problems also. In past, almost no effort has been done to overcome the aforementioned problems of L-2pc protocol. This paper is an attempt to propose a Serial Parallel linear and Fast-paced recovery-centered Transaction (SP-LIFT) commit protocol by modifying the L-2pc. It gives autonomy to the participating cohorts by informing the cohort-in-doubt about the distributed transaction’s state instead of always looking for the coordinator’s stand. The SP-LIFT protocol is also different from LIFT protocol by allowing the second phase of commit processing to go in parallel while keeping the first phase of the commit processing the same as it was in the LIFT protocol. In this way, the SP-LIFT protocol allows the distributed transaction to complete its commit processing earlier as compared to the L-2pc and LIFT protocols. The performance results also confirm that the proposed protocol will be a better alternative. © 2020, Springer Nature Singapore Pte Ltd.
