DeepO: A Learned Query Optimizer
Luming Sun, Tao Ji, Cuiping Li, Hong Chen · Proceedings of the 2022 International Conference on Management of Data · 2022
Query optimization is crucial for the query performance of database systems. Despite decades of efforts from both research and industrial communities, query optimization remains one of the most challenging problems. Thanks to the advances in artificial intelligence, data-driven and learning-based techniques are seeing traction in database research recently. However, most former learning-based works perform less practical because they are evasive about the interaction between learning components and database systems.
