'Spring and hibernate. Transaction to both data sources
In my application I need to perform several calculations on entity A, B, C. Due to entity C having a structure suited better for MongoDB I want to perform and commit transaction for entity A and B to oracle db and then entity C to mongo. However, if for any reason JVM crashed after commiting transaction to entity A, and B and commiting to mongo it will lead to incosistent database state. Is there any solution that I could use? I was thinking about using tempomary file that would be created before commiting to the oracle
