Subject [jira] [Commented] (ATLAS-487) Externalize tag in search method

Hemanth Yamijala commented on ATLAS-487:
----------------------------------------

Thanks for the confirmation. This is interesting because we have a very similar requirement
that is going to be spelt out in more detail in ATLAS-491. For us though, partitioning the
metadata objects is only one of the possible applications of what we plan to do with the framework
being built in ATLAS-491. The specifics may differ but the intent would be the same.

> Tagging metadata (or adding traits to metadata) can be used for classification of metadata
and metadata partitioning for multi-tenancy purpose or partition based on the organization
hierarchy. In these use cases, it would be ideal if I can pass the trait as a separate parameter
to the search method, instead of including the tag as a predicate in the query string. 
> If I have a complex query that retrieves metadata from multiple types, then the query
becomes more complex if I need to add predicates for the tags for all the types that are used
in the query.
> Externalizing the tag from the search query would also lead to better structure for the
client code, because I can add the classification or partition to the query without modifying
the query.
