In-Memory Performance for Big Data (2014) [pdf]

Has this pointer swizzling concept been adapted by any big data-focused databases?<p>Would be interesting to see how this works with bigger pools of volatile and persistent memory (disclaimer: I work at Intel on Optane DC SSD&#x2F;PM-related things).

Had to look this up:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Pointer_swizzling" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Pointer_swizzling</a>

Interesting, sounds a bit like the way write-barriers made the combination of copying garbage collectors and direct object pointers feasible.
