Pierre Padovani commented on ATLAS-1764:
----------------------------------------
My use case:
Consider a composite metadata entity that is made up of many (50-70+) Atlas
entities. This composite entity is pulled in order to drive a portion of a data
pipeline. The composite might contain things like:
* tables
* columns
* config
* target system information
Individually, the small Atlas metadata entities are useless to the data
pipeline, only if the runtime engine has all of the metadata required will it
be able to function. Currently composing and decomposing an entity such as
this requires specialized code that understands how to traverse and retrieve
all of the pieces. Implementing a form of entity collection would allow for the
creation of these types of composed metadata sets that could be retrieved etc.
far easier.

> ---------------
> a. Create collection(s) with attributes, constraints
> b. Update existing collection(s)
> c. Delete collection(s) - soft delete, hard delete
> d. Retrieve collections by id, name
> e. Add entity(s) to collection(s)
> f. Remove entity(s) from collection(s)
> g. Associate classification(s) to collection(s)
> h. Disassociate classification(s) from collection(s)
