This skill provides comprehensive guidance for BigQuery services, optimizations, and data handling. It acts as a routing table for specialized BigQuery topics.

[!IMPORTANT] For general standards on running BigQuery in notebooks (SQL cells, export keyword), see @skill:notebook-guidance.

[!IMPORTANT] You MUST check the data size before deciding on which libraries to use. Use the data size to justify your decision.

Refer to the following resources for expert guidance on specific BigQuery features:

1. Query Optimization

Performance and efficiency guidelines for BigQuery SQL. Includes rules for column pruning, pushdown, and materialization strategies. - Guide: OPTIMIZATION.md

2. BigFrames (BigQuery DataFrames)

Guidelines for generating valid BigFrames code for data manipulation, model development, and visualization. - Guide: BIGFRAMES.md

Bigframes should be the default library/tool as it is more efficient than using the BigQuery Python client library.

3. BigQuery ML & AI Functions (BQML SQL)

Usage rules and syntax standards for all BigQuery AI/ML functions via SQL (Forecasting, Generative AI, Classification, etc.). - Guide: BQML.md - Functions Reference: - AI.FORECAST - AI.EVALUATE - AI.GENERATE_TABLE - AI.GENERATE_EMBEDDING - Remote Models CONTRIBUTION_ANALYSIS VECTOR_SEARCH

4. Notebook SQL cells
