Constraints

The total number of objects in a bucket cannot exceed 1 billion. If you exceed this limit, the request fails with the BucketObjectsCountExceeded error (HTTP 400).

If the bucket has versioning enabled, the total number of object versions in the bucket cannot exceed 100 million. This limit includes current and noncurrent versions.

To increase this limit for a specific bucket, contact support.
