Craig L Russell reassigned JDO-651:
-----------------------------------
Assignee: Matthew T. Adams
JDO was designed to support non-SQL datastores. In fact, the first RI was a
distinctly non-SQL implementation, essentially a key-value store.
What needs to be done for NoSQL in general is to go through the specification
in detail and highlight those parts that cannot now be implemented reasonably
by a key-value store, or a non-transactional datastore.
NoSQL is probably too big a description of the kinds of datastores that makes
sense for JDO to support. Part of the exercise should be to categorize the
NoSQL datastores to focus on those categories that make sense for JDO.
> Modify specification to address NoSQL datastores

> Key: JDO-651
> URL: https://issues.apache.org/jira/browse/JDO-651
> Project: JDO
> Issue Type: New Feature
> Components: api2, specification, tck2
> Reporter: Matthew T. Adams
> Assignee: Matthew T. Adams
>
> There is increasing interest in NoSQL datastores (Google BigTable, Apache
> HBase, VMWare Redis, etc), which not only do not support SQL, but also do not
> necessarily provide support for traditional consistency or queriability
> features or guarantees, instead offering features like eventual consistency,
> key-value storage mechanisms, etc.
> This request is to modify the JDO specification (and TCK & RI) so that it
> relaxes certain portions of the specification, perhaps in the form of
> profiles similar to JavaEE 6 profiles, to allow datastores that may not
> support queries in general, do not support the ACID requirements, or that
> support key-value-based storage mechanisms to be JDO-compliant. Additions to
> the specification may also be needed in order to directly address NoSQL-type
> datastores, in a manner similar to its treatment of relational persistence
> mechanisms.
> Additionally, this request would serve to better support persistence on micro
> platforms where consistency, queriability, etc, may not be supported.
