Entrusting data storage to a vibe coded filesystem seems imprudent.

Here is my unsolicited advice:

If one of your goals is to get others to adopt the software, I recommend you redo the marketing page and readme from scratch. Delete them without looking at them again, then hand write the content for them. Once you have the content, you call tell an LLM to format it into a nice landing page, but strictly keep your wording without changes.

Eikon•45m ago
That's fair advice, thanks.

> The test suites run in public CI.

> Each card links to the CI pipeline.

Thanks for being explicit, AI written marketing site. Wouldn't have been able to figure that out! Every currently maintained and reasonably popular open source project either runs CI in public or makes the tests extremely easy to run.

I got the same vibe from

> These are asciinema recordings of real terminal sessions, rendered as text rather than video. Playback caps idle pauses at two seconds and changes nothing else.

Thanks? This sounds like it's the LLM's response to the prompter, not something you should display on the page itself...

dizhn•1h ago
I feel bad for actually liking that part now. Capping pauses at 2 seconds would show you where it hung 2+ seconds without wasting your time. Smart I thought.
Eikon•1h ago
Thank you for the feedback, the idea behind this was to say "We make claims that are backed by workflows you can verify". I'll improve the phrasing.

Under the hood, S3's storage nodes are also built on a log-structured file system: https://cdn.amazon.science/77/5e/4a7c238f4ce890efdc325df8326...

(Not posix compliant because it doesn't need to be.)

See also: JuiceFS, S3FS, and quite a few others.

We have done loads of research into using object storage wherever we can (given how cheap it is compared to SSDs), and so far it seems like making your application object store-aware is a far surer bet than abstracting S3 behind the file system. The behavior is just too different.

I'm more interested in applications that cleverly use object storage, e.g. AutoMQ, which is quite compatible with Kafka APIs but needs no HDDs.

the8472•1h ago
s3fs doesn't provide posix semantics. It's good enough™ for some uses, but not comparable to what this one is ostensibly providing.
coxley•1h ago
From the docs:

> ZeroFS fetches object data in 128 KiB parts

Read/write operations in object storage are _far more_ expensive than stored bytes. I'm always afraid of anything that abstracts over S3/GCS access specifically for that reason.

throw1234567891•53m ago
Especially that the “one fetch” is who knows how many reads and retries under the hood.
karakanb•45m ago
One of the reasons why ZeroFS seems interesting is they use SlateDB under the hood, which optimizes the requests that hit S3 behind the scenes.
preetham_rangu•55m ago
How does this compare to JuiceFS or SeaweedFS in terms of metadata latency? The LSM tree approach is interesting but compaction pauses on a remote-backed store seem like they could be painful.
tribal808•51m ago
I’ve seen things like this before; your key differentiator needs to be efficiency and safety compared to other options.
felooboolooomba•27m ago
OP this is the best advice here.

Since you are harnessing the sorcery of AI, have it write really good benchmarks, run tests and comparisons on competitive products, (and publish them), look up common pitfalls, often requested features, run security analysis.

Also with marketing texts, write your self first and then you can ask AI to hone it or give you feedback. AI slopped marketing text is visible from miles and really, really puts people off. Even if the product itself would be fine, there is some much slop slushing around in the pipes at the moment.

I really like this project and want to see it succeed! Don't let naysayers wear you down.

Eikon•22m ago
Thank you, appreciated!
ChocolateGod•49m ago
I believe the first version of this required the metadata to be stored on the ZeroFS server, making HA kinda hard.

This has changed now that if I stop the server and create a new instance with the same configuration file it'll pickup the existing metadata from the bucket?

Eikon•31m ago
> I believe the first version of this required the metadata to be stored on the ZeroFS server, making HA kinda hard.

Metadata has always been in the bucket itself.

For HA, there's now a "replicated mode" if you want automatic failover:

rockwotj•42m ago
The sub-millisecond writes with data in S3 is false and impossible. If you look at the benchmark the fsync is not timed, so this is just the latency of either the network or in kernel file operations depending on the mount settings
xyzzy_plugh•34m ago
I hate it when databases celebrate their performance without synchronous flushing. You should be clear about data loss window (which should be zero for committed transactions by default!) and the flushing interval to persistent storage.

I'm okay if you batch writes, I'm okay if you offer a low-latency mode with less durability, but by being unclear about this it just feels like a scam.

rockwotj•21m ago
Yeah in this case the footnote to the write latency specifically says “at rest in S3”, which is what caused me to go look at the source. To be clear I have no problem with the ZeroFS of only flushing on fsync.

I am very excited for object storage first systems like this to leverage low latency zonal storage for write ahead logs to keep the disaggregated storage but greatly reduce write latency. That ends up being more expensive, but is likely a good tradeoff in lots of cases I have seen

Eikon•13m ago
ZeroFS aims to be a POSIX filesystem, the semantics here are the standard ones (ext4, xfs behave the same): write() is buffered (that's the batching) and "committed" maps to fsync(), which returns only once data is durable.
rockwotj•3m ago
Nothing wrong with that, but you should remove the “at rest in S3” footnote from the write latency on the frontpage of the website, because that is not what is measured
chillfox•3m ago
I don’t get why they went for NFSv3, v4 is quite old and I can’t think of any reason why you would choose v3 over v4.
