on HN thread 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. [this video]
General overview of single-thread allocation strategies; quick watch, makes you want arenas.
