JPA: Optimistic locking and concurrency

Tweet

The JPA provides a relatively easy way to persist objects, however, there are certain cases that often require a deeper understanding of the consequences that can take place. In two recent posts, Carol McDonald and Felipe Gaucho walk you through two such cases. Carol McDonald first discusses concurrency and locking in the context of the new JPA 2.0 version, while in a second post Felipe Gaucho talks about optimistic locking in the current JPA release and what's in store on this same topic for JPA 2.0
