Abstract: The use of deep learning for database optimization has gained significant traction, offering improvements in indexing, cardinality estimation, and query optimization. However, acquiring high-quality training data remains a significant challenge. This paper explores the possibility of using generative models, such as GPT, to synthesize training data for learned database components. We present an initial feasibility study investigating their ability to produce realistic query distributions and execution plans for database workloads. Additionally, we discuss key challenges, such as data scalability and labeling, along with potential solutions. The initial results suggest that generative models can effectively augment training datasets, improving the adaptability of learned database techniques.
