Summary of Changes

Hello @tswast, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the documentation for the page_size parameter in the query_and_wait method of the BigQuery client library. The update provides crucial clarity by specifying which BigQuery API calls are influenced by this parameter, ensuring users have a precise understanding of its scope and preventing potential misinterpretations regarding its effect on the BigQuery Storage Read API.

Highlights

• Documentation Clarity: Clarified the behavior of the page_size parameter within the query_and_wait method's documentation.
• API Scope: Explicitly stated that the page_size parameter only affects jobs.query and jobs.getQueryResults API calls, and not the BigQuery Storage Read API.

Code Review

This pull request adds a helpful clarification to the page_size parameter's docstring in the query_and_wait method. The change correctly specifies that page_size only impacts jobs.query and jobs.getQueryResults API calls, and not downloads using the BigQuery Storage Read API. This is an accurate and valuable improvement to the documentation. The change looks good.
