S3 CRR and objects locks
0
A customer is building a DR architecture, using S3 CRR to copy its data to another region. All the infra is replicated (at small scale) in the DR region.
The source S3 bucket is accessed by a SFTP server doing read/write operations. So there is another SFTP server in the DR region, pointing to the CRR bucket, ready to take over if DR occurs.
Question:
Is there any kind of locking on the CRR done by the CRR process, preventing access from the DR SFTP server to the CRR bucket ?

The S3 Consistency model applies, with no object locks between writes. See more details here: https://docs.aws.amazon.com/AmazonS3/latest/dev/Introduction.html#ConsistencyModel.
