             Summary: Create RepeatedKeyInfo structure to be saved in deletedTable
                 Key: HDDS-2161
                 URL: https://issues.apache.org/jira/browse/HDDS-2161
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Dinesh Chitlangia
            Assignee: Dinesh Chitlangia


Currently, OM Metadata deletedTable stores <Key Name, OMKeyInfo>

When a user deletes a Key, <key name, omKeyInfo> is moved to deletedTable.

If a user creates and deletes key with exact same name in quick succession repeatedly, then old <key name, omKeyInfo> can get overwritten and we may be left with dangling blocks.

To address this, currently we append delete timestamp to keyname and preserve the multiple delete attempts for same key name.

However, for GDPR compliance we need a way to check if a key is deleted from deletedTable and thus given the above explanation, we may not get accurate information and it must also confuse the users.

 

This Jira aims to:
 # Create new structure RepeatedKeyInfo which allows us to group multiple KeyInfo which can be saved to deletedTable corresponding to a keyname as <KeyName, RepeatedKeyInfo>
 # Due to this, before we move a key to deletedTable, we need to check if key with same name exists. If yes, then fetch the existing instance and add the latest key to the list, store it back to deletedTable.
