[hibernate-dev] [OGM] More info for Cassandra and MongoDB datastores and dialects

[Guillaume SCHEIBEL]

Hi all,

About the collection of embeddable, currently this feature is not
developped but you can store an embeddable in the document itself (and an
embeddable inside of another embeddable etc). I'll work on the collections
/ associations stuff as soon as I'll have finished the test part with
OGM-132, OGM-138 and OGM-139.

Cheers,
Guillaume
