Unveiling the Game-Changing PostgreSQL Patch: A Leap Forward for 1C:ERP
Introduction
Welcome to our latest deep dive into the world of PostgreSQL, where we explore a revolutionary patch that promises to transform the month-end closing process in 1C:ERP. This patch, presented at PgConf 2025, has captured the attention of developers and tech enthusiasts alike, offering a tenfold increase in speed. Let’s unravel the details and implications of this exciting development.
The Context: PgConf 2025
PgConf 2025, the premier event for PostgreSQL enthusiasts, recently concluded with a buzz around a particular patch. This patch, introduced in the talk «Fast Month-End Closing in 1C:ERP on PostgreSQL,» promises to significantly enhance the efficiency of month-end processes in 1C:ERP, a popular enterprise resource planning software.
Understanding the Patch
What is 1C:ERP?
1C:ERP is a comprehensive enterprise resource planning software widely used in various industries. It relies on PostgreSQL for its database needs, with specialized builds tailored for optimal performance.
The Challenge
Month-end closing in 1C:ERP is notoriously time-consuming, often requiring multiple attempts due to accounting errors. Users typically engage with the application every 20 minutes, with the closing process taking hours.
The Solution: A Secret Patch
The patch, developed by Fedor Sigaev, addresses a critical inefficiency in query execution. It replaces the Nested Loop join method with a Hash Join for many queries, significantly reducing execution time. The Nested Loop method often underestimates the number of rows, leading to slow performance.
The Impact
Performance Boost
The patch accelerates month-end closing by a factor of ten, a remarkable improvement that caught the attention of conference attendees. Despite its potential, the patch remains unofficially released, sparking curiosity and demand among developers.
Technical Insights
- Nested Loop vs. Hash Join: The patch shifts from Nested Loop to Hash Join, optimizing query execution.
- Query Planner Adjustments: The planner’s tendency to default to Nested Loop is addressed, preventing performance bottlenecks.
Community Reactions
The presentation sparked lively discussions among attendees, with many eager to implement the patch. Fedor Sigaev assured the community that the patch is open and available, a rare gesture in today’s competitive tech landscape.
Conclusion
The unveiling of this patch at PgConf 2025 marks a significant milestone for 1C:ERP users and PostgreSQL developers. By addressing a longstanding performance issue, this patch not only enhances efficiency but also exemplifies the collaborative spirit of the open-source community.
Tips for Developers:
- Stay Informed: Keep an eye on community forums and commit fests for updates on the patch’s official release.
- Experiment and Share: If you compile PostgreSQL versions independently, consider testing the patch and sharing your findings with the community.
In a world where efficiency is paramount, this patch offers a glimpse into the future of database management, where speed and accuracy go hand in hand. Stay tuned for more updates as this exciting development unfolds.
