描述

Currently when you query a RECORD field type, you will get some weird object in the query output (see example). Instead we need to deconstruct it into separate columns (field.sub_field) like we do for MongoDB.

研究方向
Investigate how Redash handles MongoDB nested fields (likely in the query runner code) and apply similar logic to BigQuery's RECORD fields. Look at the BigQuery data source implementation in the Redash codebase, e.g., redash/query runner/big query.py. Check the existing MongoDB handling for reference in redash/query runner/mongodb.py. Ensure that sub fields are expanded into separate columns with dot notation.
