(preview) OGM-140 OGM-141 table exposed to DatastoreProvider and embeddable collection info provided to AssociationKey

[emmanuelbernard]

I have been working on two things lately

Expose table and column information to the DatastoreProvider

This is useful to build the right buckets in some NoSQL engines. In particular Cassandra can now use
specific tables instead of the generic one we are using currently.
Let me know how it works.

Expose infos on collection of embedded to AssociationKey

One thing I want out of the MongoDB Dialect is the ability to store collections of embeddable within the entity document itself instead of in a different document. I have added a couple of information to AssociationKey in that effect:

• the collection role
• the owner's entity key
• the type of association

To the MongoDB writers, let me know if the information is useful and if you can store collections of embeddable within the entity document itself.

this was rebased, code adjusted for some needed changes after rebase (mostly TestSuite helpers changed), merged.
