The following list describes which security and access control features and functionality are unsupported or limited for S3 Tables.
-
Public access policies are not supported. Users can't modify bucket or table policies to allow public access.
-
Presigned URLs to access objects associated with a table are not supported.
-
Tags are not supported for table buckets and tables. Therefore, support for attribute-based access control and tag-based allocation is unavailable.
-
Requests made over HTTP are not supported. Amazon S3 automatically responds with an HTTP redirect for any requests made via HTTP to upgrade the requests to HTTPS.
-
You must use AWS Signature Version 4 when making requests to an access point by using the REST APIs.
-
Requests made over the Internet Protocol version 6 (IPv6) are supported only for object-level actions over table storage endpoints, and not for the table- and bucket-level actions.
-
Table bucket and table access policies are limited to 20 KB in size.
