Module source 

Execution plan for reading Arrow IPC files

Naming Note

The naming in this module can be confusing:

• ArrowFileOpener handles the Arrow IPC file format (with footer, supports parallel reading)
• ArrowStreamFileOpener handles the Arrow IPC stream format (without footer, sequential only)
• ArrowSource is the unified FileSource implementation that uses either opener depending on the format specified at construction

Despite the name “ArrowStreamFileOpener”, it still reads from files - the “Stream” refers to the Arrow IPC stream format, not streaming I/O. Both formats can be stored in files on disk or object storage.
