Additionally there will be changes in how tags are propogated to ranger in that whilst today you just associate a tag (classification) with an entity, it's more useful often to associate the classification with a business term, and then associate that with the entity. The changes up from the core atlas, will go through a new API (ATLAS-1696) and changes in ranger (RANGER-1454) - if approved (this is still work in progress/unreviewed thus far), so feel free to engage in the discussions there too. In terms of in general inheriting the classification ... overrides will IMO be needed (as David mentions) since sometimes a derived table will require the same classification, for example around confidentiality, whilst other times data could be combined and need a HIGHER classification whilst in other cases data may be redacted, requiring a LOWER classification ;-) Regards Nigel.
Re: Can be tags inherited?
Hi Peter, We have recently added RelationshipDefs, as the way to inject new relationship attributes into entities. The relationship def can specify whether tags propagate across the relationship and in which direction. The actual tag propagation is not in the code base yet, but is being worked on. Tag propagation will not result in copies of tags - that could be become difficult to manage - instead as you query entities, the Atlas code will derive the tags associated with an entity. We have not designed yet how to override this behaviour, when the propagation behaviour in the Def is not appropriate. I have not got the Jira number for this : by copy Madhan - do you have this for Peter. We feel this feature will allow more consistent control on how tags are applied to entities and in what circumstances; it therefore simplifies tag authoring. all the best, David. From: Peter Gergo Barna To: "dev@atlas.apache.org" Date: 12/07/2017 04:32 Subject: Can be tags inherited? Hi All, I have a question about the possibility of Atlas automatically apply tags based on lineage relations. Let's suppose we have a hive table tagged as 'secret'. Can we have Atlas automatically apply this tag on all entities derived form this table, e.g. all views selecting from this table?
