The Low-Level Persistent Library (LLPL) is an open source Java library being
developed by Intel for persistent memory programming. By providing Java access to
persistent memory at a memory block level, LLPL gives developers a foundation for
building custom abstractions or retrofitting existing code.
The higher-level Persistent Collections for Java (PCJ) offers developers a range of
thread-safe persistent collection classes including arrays, lists, and maps. It also offers
persistent support for things like strings and primitive integer and floating-point types.
Developers can define their own persistent classes as well.
