Subject [jira] [Commented] (ATLAS-635) Process showing old entity name where as actual entity is renamed.
Date Mon, 23 May 2016 08:25:12 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-635?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15296090#comment-15296090

Vimal Sharma commented on ATLAS-635:
------------------------------------

Let's consider one of the proposed solutions:
Source ----> Process(with old name) ----> Target(old entity name + marked as delete)
---> Process(rename from old to new) ---> Target(with new entity name)

This solution will result into creation of a new entity when table is renamed. When we create
a new entity for the table, all traits and audit events associated with original table are
lost. The desirable outcome would be to retain all traits/audit events associated with the
table.

The second solution is better suited for the case. We can add a new attribute "alias" which
will maintain a list of all previous tablenames.

> Process showing old entity name where as actual entity is renamed.
> Example:
> 1. Create table as select.
> 2. Rename the target table to new name.
> 3. Now check the lineage: The process is still showing the old table name where as the
target table is changed. This is confusing from customer perspective.
> One possible solution is:
> Source ---->   Process(with old name) ----> Target(old entity name + marked as
delete) ---> Process(rename from old to new) ---> Target(with new entity name).
