It is of course important to point out that this is akin to casting a struct to a void pointer and writing it to a file (it's just faster), which works extremely well but requires the data structures to have a stable memory representation. If one changes the structs in any way, old persistent data will look like garbage. One should therefore still have an extremely well-defined and versioned system for managing persistent data, rather than just arbitrarily allocating objects on the persistent heap.

It's still neat, though.

Yup. In this aspect libpmemobj could be compared to how Cap'N Proto [0] works. And of course, this has some trade-offs that users need to be aware of.
