No no, you're actually the only one who could possibly know.

Doea it happen on nightly?

Well, we need to get something much smaller and reproducible. But I have the gut feeling this is not gonna be easy.

Do you have any evidence of the improvement in more standard situation—uncompressed file system, physical drive? I'm concerned about having dozens of parallel reads. It is possible that a today's...

@zommiommy is this already happening?

Yes, it's the same. Since it's a cumulative stored by deltas, the important thing is that when concatenating you strip the first zero from every batch except the first.

In fact, the responsibility of writing the offsets should be delegated to the Encoder in the current architecture.

Well, the only difference should be in the generation and inversion of the permutation. The problem is that CompactArray in the atomic version does not have very strong concurrency guarantees,...

Yes, `iter_from` and `iter_to` seem more in line with the rest of the software. What's the failed check? BTW, thanks for the impl.

Luca, if you could follow [these guidelines](https://github.com/vigna/rust-dev-guidelines) that would be great. In particular, documentation is in third person. But I see that now even a normal iterator uses twice the...
