We strongly advise using S3 object paths rather than file names to extract metadata (e.g., year, exchange, instrument).
⚠️ Current vs Proposed File Names
- Old: Filenames contain metadata and are human-readable.
- New: Filenames use generated IDs; metadata is stored in the S3 path.
✅ Why It Matters
- More stable, structured access.
- Avoids breakage from file naming changes.
- Simplifies workflows.
🛠️ What You Should Do
If you currently parse filenames, update to extract metadata via the object path instead.
