| ## Reference material | ||||
| ## Design | ||||
|  | ||||
| [DESIGN.md](DESIGN.md) - DESIGN.md contains a fully detailed dive into how | ||||
| littlefs actually works. I would encourage you to read it since the | ||||
| solutions and tradeoffs at work here are quite interesting. | ||||
| At a high level, littlefs is a block based filesystem that uses small logs to | ||||
| store metadata and larger copy-on-write (COW) structures to store file data. | ||||
|  | ||||
| [SPEC.md](SPEC.md) - SPEC.md contains the on-disk specification of littlefs | ||||
| with all the nitty-gritty details. Can be useful for developing tooling. | ||||
| In littlefs, these ingredients form a sort of two-layered cake, with the small | ||||
| logs (called metadata pairs) providing fast updates to metadata anywhere on | ||||
| storage, while the COW structures store file data compactly and without any | ||||
| wear amplification cost. | ||||
|  | ||||
| Both of these data structures are built out of blocks, which are fed by a | ||||
| common block allocator. By limiting the number of erases allowed on a block | ||||
| per allocation, the allocator provides dynamic wear leveling over the entire | ||||
| filesystem. | ||||
