研究方向
Examine the existing BigQueryIO implementation in the Java SDK (specifically the write and read transforms). Understand the BigQuery clone table API from Google Cloud documentation. Look at the comments and any linked discussions in issue #38310 for design input. Propose a new transform following the pattern of existing IO operations, considering table cloning semantics and error handling.
