UniHeap: Managing Persistent Objects Across Managed Runtimes for Non-Volatile Memory
[article]
2022
arXiv
pre-print
Preserved Fulltext
It proposes a unified persistent object model that supports various managed languages, and manages NVM within a shared heap that enables cross-language persistent object sharing. ...
UniHeap reduces the object persistence overhead by managing the shared heap in a log-structured manner and coalescing object updates during the garbage collection. ...
• We present a shared NVM heap for managing persistent objects. ...

With significant experience in managing actual production data under our belt, we are now in a position to recraft the system to better suit current needs. ...
The persistent event storage system has remained largely unchanged since the initial implementation, and thus includes many design features which have become performance bottlenecks. ...
Acknowledgments We wish to acknowledge David Quarrie and Simon Patton for their work on the original BaBar event store [1] . ...

Therefore, sharing a PMO beyond the application bounds to other applications or scientists requires storing the persistent pointer of PMO. ...
Our key contributions in this paper are: • We propose an application framework for PM to store and access memory objects via persistent pointers beyond the application lifetime and to share objects across ...

The first, persistence with modules, relies on static binding to objects in the persistent store (By 'object', we mean the concrete representation of a value). ...
The second, stream persistence, provides a more flexible mechanism which supports dynamic binding to objects in the persistent store. ...
Acknowledgements We are indebted to Fred Brown for providing the persistent storage system [Brow89] which underlies Staple and to our colleagues at St Andrews for their valuable comments. ...

Following these rules, languages may be designed that provide persistence as a basic abstraction. ...
Persistent programming is concerned with creating and manipulating data in a manner that is independent of its lifetime. ...
Figure 5 illustrates a data structure where one of the components is pointed at or shared by two others. This sharing should be preserved within the persistent store. ...

In this work, we developed a Heap-Based Persistent Object Store (HEAPO) to manage persistent objects in byte-addressable Nonvolatile RAM (NVRAM). ...
HEAPO defines its own persistent heap layout, the persistent object format, name space organization, object sharing and protection mechanism, and undo-only log-based crash recovery, all of which are effectively ...
Update consistency for a shared persistent object is guaranteed since the HEAPO library synchronizes the accesses to the shared object metadata with a lock. ...

Object persistence plays a key role in designing data model, business objects working with other business objects. Object persistence could be very efficient if designed correctly. ...
A typical design leads extra overheads in terms of cost, resource utilization, and time. Considering the importance of object persistence, it is very essential to concentrate more on this area. ...
The data store schema that is used to store the persistent state of the objects in the data store is different from the objects having a different model (object-oriented) for an application. ...
