I didn't find any way how to enable Attribute Based Access Control for S3 objects if I need to assign more tag values than one S3 Tag can support:
... tag values can be up to 256 Unicode characters in length. AWS Docs
For example, if I need very fine-grained ABAC to mark an S3 object with 1000 IDs in the Tag Value of the Tag Key IDs, then I will overreach the maximum 256 characters, e.g. IDs=1,2,3,4...999,1000
What can be a solution of that problem?
