In some areas, especially hard real-time/embedded or safety critical, dynamic memory allocation is strongly frowned upon, and for good reasons.

Even if your application does not have stringent safety/predictability requirement, following the principles of Data Oriented Design leads naturally to a radically different approach to memory management.

I am glad to see this kind of projects and design choices.

Thanks!

Data Oriented Design runs like a river through TigerBeetle—it's always on our mind.

By the way, have you seen Andrew Kelley's Handmade Seattle talk on Practical DOD? [1]

Yes, I've seen this one, and a few others.

I think DOD should be more like an engineering mindset than a strict set of rules.

From my experience it can be impractical/cumbersome, especially when prototyping because DOD usually pays off in the long run.
