Fifty Years of Transaction Processing Research (extended)

2026-05-19

AI Summary

Although transaction processing is often regarded as a “solved” problem, it has continuously evolved over more than fifty years. This work offers a systematic examination of its foundational theories, system implementations, and paradigm shifts through both historical retrospection and forward-looking reflection, uncovering the core drivers behind its sustained development. Drawing on early milestones and the authors’ firsthand experience, the paper not only reaffirms the enduring relevance of transaction processing in modern data systems but also identifies several unresolved challenges. In doing so, it provides a clear historical context and strategic guidance for future research directions in the field.

Abstract

In this short paper, I recount some early history of transaction research (including some of my own), explain why transaction research continues to this day (even though it seems to be a solved problem), and speculate about its future. This is an extended version of the paper that appeared in the Companion of the 2025 International Conference on Management of Data (SIGMOD-Companion '25).
