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.
