------------------------------------
Summary: Tag propagation from object to child object or derivative
asset
Key: ATLAS-2469
URL: https://issues.apache.org/jira/browse/ATLAS-2469
Project: Atlas
Issue Type: New Feature
Reporter: pratik pandey
Assignee: pratik pandey
User Story:
As a data steward i need a scalable way to quickly and efficiently propagate
tags for efficient searches and tag based security. Likewise tags for
derivative dataset should be inherited from the parent. For example, if an
entity is tagged "Secret" then resulting entity created from a CTAS operation
should also be tagged "secret" to maintain the classification of the parent. In
the case where 2 or more datasets are aggregated the derivative dataset should
be a union of all parent tags.
Terms:
* Child business terms should inherit the tags associated with the parent term.
* the option to propagate tags to child business terms in a hierarchy should be
provided
* Ability to update the propagated tags manually via UI or through the API
* Tagging a term should propagate to data assets that are already attached to
that business term as well
Data assets
* For supported components in HDP 2.6,if a derivative asset is created it
should inherit the tags and attributes from the original asset.
* the option to propagate tags to child entities should be provided (e.g. if
you tag a hdfs folder optionally tag all the files within it)
* Ability to update the propagated tags manually via UI or through the API
* Tagging a parent object should be inherited even after child creation
dynamically (unless a flag is set not to do this)
* Derived data assets should have the tags of the original data asset.
conflict resolution - if the different values for attributes then a UX dialog
that prompts user for action needs to be provided. Once resolved, the resolved
value will be carry forth to derivative dataset.
