Concurrency - The Fly in the Ointment?

Concurrency is a central pillar of the Java programming language, is implicit in the transactional model of computation adopted by most persistent systems, and has been widely studied in the context of orthogonal persistence. We argue that despite the substantial literature on concurrency control and transaction models for orthogonal persistence, a basic question as to the interaction between concurrency and orthogonal persistence has yet to be adequately addressed. The demands of orthogonality appear to place orthogonal persistence at odds with more general approaches to concurrency control. Given its stated objective of providing a `complete' computational environment, the future of the orthogonal persistence vision in general, and persistent Java in particular, will depend, to some extent, on the release of this tension through the realization of new approaches to the integration of concurrency and persistence. This paper addresses both strict transactional and more `open'...
