TFS

Top Pro

Concurrent

TFS contains very few locks and aims to be as suitable for multithreaded systems as possible. It makes use of multiple truly concurrent structures to manage the data, and scales linearly by the number of cores. This is perhaps the most important feature of TFS. See More

Top Con

Not ready for use

While many components are complete, TFS itself is not ready for use. See More

Top Pro

Usable in other systems

It was never planned to be Redox-only. See More

Top Pro

Revision history

TFS stores a revision history of every file without imposing extra overhead. This means that you can revert any file into an earlier version, backing up the system automatically and without imposed overhead from copying. See More

Top Pro

Data integrity

TFS, like ZFS, stores full checksums of the file (not just metadata), and on top of that, it is done in the parent block. That means that almost all data corruption will be detected upon read. See More

Top Pro

Copy-on-write semantics

Similarly to Btrfs and ZFS, TFS uses CoW semantics, meaning that no cluster is ever overwritten directly, but instead it is copied and written to a new cluster. See More

Top Pro

O(1) recursive copies

Like some other file systems, TFS can do recursive copies in constant time, but there is an unique addition: TFS doesn't copy even after it is mutated. How? It maintains segments of the file individually, such that only the updated segment needs copying. See More

Top Pro

Guaranteed atomicity

The system will never enter an inconsistent state (unless there is hardware failure), meaning that unexpected power-off won't ever damage the system. See More

Top Pro

Improved caching

TFS puts a lot of effort into caching the disk to speed up disk accesses. It uses machine learning to learn patterns and predict future uses to reduce the number of cache misses. TFS also compresses the in-memory cache, reducing the amount of memory needed. See More

Top Pro

Better file monitoring

CoW is very suitable for high-performance, scalable file monitoring, but unfortunately only few file systems incorporate that. TFS is one of those. See More

Top Pro

All memory safe

TFS uses only components written in Rust. As such, memory unsafety is only possible in code marked unsafe, which is checked extra carefully. See More

Top Pro

Full coverage testing

TFS aims to be full coverage with respect to testing. This gives relatively strong guarantees on correctness by instantly revealing large classes of bugs. See More

Top Pro

Improved garbage collection

TFS uses Bloom filters for space-efficient and fast garbage collection. TFS allows the FS garbage collector to run in the background without blocking the rest of the file system. See More

Top Pro

SSD friendly

TFS tries to avoid the write limitation in SSD by repositioning dead sectors. See More

Top Pro

Full-disk compression

TFS is the first file system to incorporate complete full-disk compression through a scheme we call RACC (random-access cluster compression). This means that every cluster is compressed only affecting performance slightly. It is estimated that you get 60-120% more usable space. See More

Top Pro

Asynchronous

TFS is asynchronous: operations can happen independently; writes and reads from the disk need not block. See More
