-------------------------------------
Hi [[email protected]],
This is a great Jira. Some up front thoughts:
- I assume a collection could have a type . For example, we could have a
collection of Hive tables.
- I am not sure what constraints and attributes you are envisaging are useful
for a collection. Maybe whether the collection is ordered might be a useful
constraint or maximum size.
- I am not sure what a classification on a collection means. It would be good
to have a use case for this.
- Is a collection going to be defined using a CollectionDef or type in
EntityDef . If suggest it be an EntityDef type if that is possible.
- Can we have an attribute pointing to a collection?
- I wonder if we can have collections in collections and allow set based
operations like unions.
