I need to check for duplicate rows across the tables in this dataset. Let me start by understanding the structure of the largest tables and then check for duplicates systematically. ```json { "action": "tool_call", "reasoning": "I need to identify potential primary keys and check for duplicates in the largest tables. Let me start by inspecting the columns of beer_ratings, the largest table with 14.3M rows, to understand what columns could serve as unique identifiers.", "tool": "inspect_columns", "args": { "table": "beer_ratings" } } ```
