> [Federation] Added JDOFederationStateStore for easy database query.
> We currently have a solution like SQLFederationStateStore, but I think the
> following places can be optimized:
> 1. We hope that the database can support Oracle and Postgres, but it is very
> difficult to provide stored procedure scripts for each database.
> It involves a lot of testing and multi-version verification. If possible, we
> hope to provide table building statements.
> 2. I read the code and found that it is basically the operation of add,
> delete, select and update a table.
> This can be done for us using the ORM framework, such as DataNucleus.
> I plan to provide JDOFederationStateStore which can easily replace
> SQLFederationStateStore.
