s3_validate_etag_on_read
Version history
| Version | Default value | Comment |
|---|---|---|
| 26.7 | 1 | New setting to detect concurrent in-place overwrites of S3/GCS objects during a read by validating the GET response ETag against the listed one. previous_value=false so `compatibility` with versions before 26.7 restores the pre-existing behavior (no validation). |
When reading an object from S3 (or an S3-compatible store such as GCS), check that every GET request returns the same ETag that was observed when the object was listed. A single file read issues many ranged GET requests; if the object is overwritten in place between them (for example by an external writer rewriting a fixed key), the reads can otherwise be stitched together from two different object generations and surface as a corrupted checksum or parse error. When a mismatch is detected the read fails with S3_OBJECT_CHANGED_DURING_READ instead of returning inconsistent data. Disable only for workloads that intentionally read objects that are being overwritten and can tolerate inconsistent reads.
