Support data integrity while using external db as the 2nd database in cuba


In Spring, there are ChainedTransactionManager to help maintain the data integrity in case that App needs to maintain two databases data integrity.

What about Cuba? Do we have any feature to support similar thing if I use an external database along with cuba’s internal db.


Hi Peidong,

We now use JpaTransactionManager which doesn’t enable any dependencies between transactions for different data stores. But we should consider what ChainedTransactionManager could bring to the table. Thanks for the hint!

I’ll create an issue in our bugtracker as soon as it get back online.
