Benjamin Feng explains the fundamentals of memory allocators, exploring different allocation strategies and how they are implemented in Zig.
From Zig SHOWTIME #5 zig.show Title Talk InterviewWhy it's here
5 people recommend thisWhat people say. Recommended as an excellent, accessible overview of single-threaded memory allocation strategies and Zig's unique approach to memory management.

On “Custom Allocators Demystified”
Would recommend watching the "What's a Memory Allocator, Anyway?" talk from Zig contributor Benjamin Feng: link to this video

On “The effect of switching to TCMalloc on RocksDB memory use”
It's interesting that I saw this post minutes after watching the talk "What's a Memory Allocator Anyway?" by Benjamin Feng. It's ostensibly about Zig's allocation schemes, but it's more of a general overview of the varied (single-thread) allocation strategies in use today. It made me really want to try out arena allocators It's a quick watch at 1.5x speed, the last third is an interview. 1. link to this video

On “Drop millions of allocations by using a linked list (2015)”
For an overview of how Zig does this and at the same time a nice overview on different types of allocators: What's a Memory Allocator Anyway? by Benjamin Feng link to this video

On “Using pointers to be gentler to RAM”
…case you want to start reading the source of such things. C is an obvious starting point. But if you're after learning about more modern allocation strategies then there's been quite a few things added to C++ over the last decade regarding allocators. And Zig has some really good stuff in the works. This talk is a good place to get up to speed.

The alternative is that you push through the user space mirror and make your way in to wonderland - something I haven't done myself so I can only parrot hearsay. But Understanding the Linux Kernel and Linux Kernel Development are two popular books mentioned in such discussions. These cover a lot of the details behind how the Kernel request…

On “Books to better understand memory allocation.”
I don't have a book recommendation, but I recommend taking a look at the video What's a Memory Allocator Anyway?. It's Zig-focused since Zig has you pass around an allocator specifically, but it's a great foundation for thinking about allocation in general IMO.

This is a Zig-related talk but is a nice introduction to arena allocators (among others)
