For anyone interested in how databases can benefit from PMem, I suggest watching this fantastic presentation from Oracle's Jia Shi "Under the Hood of an Exadata Transaction – How Did We Harness the Power of Persistent Memory"

There's a company in Europe, Saule Technologies [1], that is claiming to be already capable of large scale commercialization of perovskites. It seems you can even buy/license it (B2B). The article seems to suggest that the biggest

The authors of the article I linked to earlier came to the same conclusions. And so did the SPDK folks. And the kernel community (or axboe :)) when coming up with io_uring. I'm just hoping that we will see software catching up.

Right, I agree. I'd go even further and say that async/await is a great fit for a modern asynchronous I/O stack (not read()/write()). Especially with io_uring using polled I/O (the worker thread is in the kernel,

Thanks for sharing this article - I found it very insightful. I've seen similar ideas being floated around before, and they often seem to focus on what software can be added on top of an already fairly complex solution (while LSM can a

What I find interesting about the performance of this type of hardware is how it affects the software we are using for storage. The article talked about how the Linux kernel just can't keep up, but what about databases or kv stores. Ar

All x86-64 CPUs support 48 bit address space, with 57 bits in the newest ones [1]. It's unlikely that address space exhaustion would be a problem for the vast majority of use cases. [1] - https://en.wikipedia.org/wiki&#

Disclaimer: I work at Intel on Persistent Memory If you are asking just about the OS interfaces - you can already emulate persistent memory with DRAM [1], which allows you to play around with the programming model. There are also NVDIMM-N d

OP here, yes - you are right, mea culpa. I'll try to correct that particular picture. Thanks for pointing it out.

With the implementation of system-ram operational mode [1] of devdax, you can just use normal linux interfaces for allocation of huge pages [2]. Those then can be seamlessly utilized by most memory allocators, with no need to modify anythin

That's an excellent question. The answer is that those type of libraries will work just fine for read-only workloads since you cannot mutate a data structure once you have serialized and written it out to a file. The best part is, this
