Siyao Meng updated HDDS-7168:
-----------------------------
Due Date: 27/Apr/23
> Prevent writes to keys that start with ".snapshot"
> --------------------------------------------------
>
> Key: HDDS-7168
> URL: https://issues.apache.org/jira/browse/HDDS-7168
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: George Jahad
> Assignee: Dave Teng
> Priority: Major
>
> The snapshot design defines a key prefix for use with snapshots:
> ".snapshot/snapshotName". Any read of a key with that prefix should be be
> read from the corresponding snapshot.
> But nothing currently prevents key writes from inadvertenly using that
> prefix, and if they do, they will not be readable.
> To prevent user confusion, we should disallow them from writing any keys with
> the ".snapshot" prefix.
> One possible approach would be to add a preExecute method to the OMKeyRequest
> class, (which is a parent of the key write commands.) That method would
> check the key and throw an invalid key error if needed. (OMKeyRequest would
> likely need to add an abstract method that each of the specific write classes
> would need to implement.)
