Aerospike Graph was discussed at Aerospike Summit 2023 by Ishaan Biswas, George Anadiotis, and Marko Rodriguez, who talked about the power of graph databases, their current market growth, and how to evaluate them. The three experts defined graph databases as a solution for handling large amounts of connected data and enabling developers to leverage the graph data model to address complex computing challenges. They also discussed various use cases such as identity graphs in AdTech, customer 360, and real-time fraud prevention. Key takeaways include adopting a paradigm shift from SQL to a graph data model, evaluating commercial solutions based on performance, scalability, cost, analytics, developer-friendliness, operational agility, and community support. Additionally, the experts highlighted challenges such as scaling graph databases, managing bidirectional pointers between vertices on different machines, and establishing in-sync cleanup mechanisms for smoother system performance.
