Hypermnesia: Auto Reconciliation in Mnesia - Code BEAM Europe 2023

Explore a conference talk from Code BEAM Europe 2023 that delves into Hypermnesia, an extension to Mnesia offering automatic conflict resolution. Learn about the limitations of Mnesia's embedded database for Erlang/OTP applications, particularly its lack of conflict resolution after network partitions. Discover how eventual consistency and CRDTs can be utilized to achieve automatic conflict resolution within Mnesia. Gain insights into the new access context async_ec introduced by Hypermnesia, which simplifies replica reconciliation after partitions. Examine the design principles behind Hypermnesia, focusing on minimizing overhead and providing out-of-the-box usage. Review benchmarking results and practical examples demonstrating the application of Hypermnesia in real-world scenarios. Understand the collaborative effort between the University of Cambridge and Erlang Solutions in developing this project. Enhance your knowledge of database management and conflict resolution techniques in distributed systems through this informative 21-minute presentation.
