Resolved after 6 hours 51 minutes, affecting Data Connector Integrations and Data Connector Integrations and 1 more, on October 22, 2026.
The issue causing Amazon S3 Parquet imports to load date and time columns as text (string) instead of numbers (long) has been resolved. A fix was deployed on October 22, 2026 at 07:40 UTC, and new import jobs load these columns as numbers (long), as before October 13, 2026. Data imported between October 13, 2026 02:00 UTC and October 22, 2026 07:40 UTC may contain affected date and time columns. We will contact affected customers directly. We apologize for the inconvenience and thank you for your patience.

Update timeline
- identified Oct 22, 2026, 03:24 AM UTC
Since October 13, 2026 02:00 UTC, some import jobs that read Parquet files from Amazon S3 complete successfully but load date and time columns as text (string) instead of numbers (long). If the destination table already defines these columns as long, the imported values are empty (NULL). Only columns stored with a date or time type in the Parquet file are affected. Other columns and other data connectors are not affected. We have identified the cause, a change introduced in the October 13 release, and are preparing a fix. We are assessing the full scope of impact. We will provide an update in 30 minutes.
