Incident Timeline

Monitoring
We have deployed a fix for Amazon S3 Parquet imports loading date and time columns as text. New import jobs load these columns as numbers (long), as before October 13, 2026. We are monitoring to ensure stability.

We will provide an update in 30 minutes.

Identified
We have identified the cause of Amazon S3 Parquet imports loading date and time columns as text (string) instead of numbers (long) since October 13, 2026 02:00 UTC, and are deploying a fix.

Until the fix is deployed, affected import jobs continue to complete with these columns loaded as text. Other columns and other data connectors are not affected. We are verifying data integrity for data imported during this period.

We will provide an update in 30 minutes.

Identified
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.
