Question

Can Segment manually edit stored archive data to overwrite corrupted events in my warehouse during a backfill?

Product

Twilio Segment

Environment

Segment Console

Answer

No, Segment cannot manually edit or overwrite historical data stored in internal archive storage. Running a warehouse backfill will re-ingest the original raw data, including any corrupted values. To update your warehouse with corrected data, you must re-send the affected events to Segment with the updated values so they can sync downstream to your warehouse.

Additional Information 

Before re-sending events, ensure your source implementation is updated so future incoming data is formatted correctly.
