A webinar featuring Martin Vo, CTO of Paysure Solutions, explores the company's adoption of Memgraph as a graph database to enhance real-time payment authorization processes. Paysure Solutions initially faced challenges with their existing architecture that used PostgreSQL and Redis, which led them to switch to Memgraph due to its stability and ability to handle complex queries efficiently. Martin shared insights into their payment authorization workflow, which operates under a strict 200-millisecond time constraint, and the benefits of Memgraph in simplifying system architecture and improving transaction handling speed. Despite not employing complex graph algorithms, the transition to Memgraph allowed Paysure to manage data more effectively, particularly in preventing duplicates and handling temporal data. The webinar also covered technical challenges, performance optimizations, and operational solutions implemented by Paysure, highlighting the advantages of using a graph database over traditional relational databases for their specific needs.
