Tame High-Cardinality Categorical Data in Agentic SQL Generation with VectorDBs

The article discusses the challenge of handling high-cardinality categorical data in text-to-SQL systems and how integrating vector databases with agentic workflows can address this issue. Traditional methods such as preprocessed database techniques and LLM-based translation often fall short when dealing with high-cardinality data, leading to a significant gap in translating natural language queries to accurate SQL. Vector databases like Milvus offer a solution by storing and efficiently querying high-dimensional vector representations of data, enabling semantic searches rather than keyword matches. By combining Waii's intelligent text-to-SQL capabilities with Zilliz Cloud's powerful vector storage, users can create robust, scalable, and accurate systems for handling high-cardinality categorical data in their text-to-SQL applications.
