However, for S3, we may not always see our own deletes. Quoting from https://aws.amazon.com/s3/faqs/ here: {quote}Q: What data consistency model does Amazon S3 employ? Amazon S3 buckets in all Regions provide read-after-write consistency for PUTS of new objects and eventual consistency for overwrite PUTS and DELETES.{quote} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
