Anu Engineer commented on HDDS-337:
-----------------------------------
[~dineshchitlangia] when ozone we being designed we looked at other cloud
storage systems like s3. Here is the guideline from S3 on the key name
character set.
[https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMetadata.html]
Bottom line: Ozone is not doing something that is radically different from S3.
So my thoughts is to stick to the current set (that is valid URI keys) as is. I
am sure OzoneFS might struggle with this, I am hoping that OzoneFS will never
create these invalid names itself.
> keys created with key name having special character/wildcard should not
> allowed
