Research direction

To implement this feature, start by examining existing SeaTunnel source connectors (e.g., in the `seatunnel connectors` module) to understand the pattern for reading and normalizing data. Consider using Apache PDFBox for PDF parsing and map extracted content to a structured format (e.g., JSON or Avro). Review the issue comments and any linked discussions for additional context, and coordinate with the assignee to avoid duplication.
