redb VS acorn

I wrote redb (https://github.com/cberner/redb) using mmap, initially. However, I later removed it and switched to read()/write() with my own user space cache. I'm sure it's not as good as the OS page cache, but the difference was only 1.2-1.5x performance on the benchmarks I cared about, and the cache is less than 500 lines of code.

exposure of the redb builder functionalities.

redb has reached its 1.0 release. The file format is now gauranteed to be backward compatible, and the API is stable. I've run pretty extensive fuzz testing, but please report any bugs you encounter.

I'm just now updating the benchmarks in the readme with multi-threaded workloads :) https://github.com/cberner/redb/pull/576

redb, but that doesn't have a stable file format yet,

I also have to support web, so I'm considering a hybrid approach with a direct IndexedDB API there and something like sqlite, percy, sanakirja, or redb on native.

Nice list, but don’t forget persy, redb and sanakirja too!

check out https://github.com/cberner/redb! it is inspired by LMDB and has comparable performance, but is entirely built in rust!

Yup, the language is immature in some domains like data replication, compilation time, lifetime expressivity, not having a default async runtime and the incompatibility of all of them. But many of these domains are worked on and improved every day this is why I love this language so much. This is because there is space for improvement. I also hope that one day we will have a pure-Rust LMDB alternative that I can contribute to without fear of C.

they are, ya! I'm quite excited about that, and already have a PR open to use GATs. It's not enough to fix this issue though, because std needs to add support for LendingIterator too

Acorn is an example Holochain app created by one of the cofounders.

Each user is effectively the server for their own data. However, many users will expect apps to work like a cloud-based system, where their data is available to others even when their computer is off. To solve this, Holo is building a hosting service based on Holochain, allowing people to offer their spare computing power for hosting others. The HOT token you may find are pre-purchase credits for this hosting. This isn’t a requirement for Holochain apps to work (and there are working Holochain apps such as Acorn). There will also be non-cryptocurrency interfaces to pay for hosting.

I've recently discovered Acorn which has a pretty cool approach to project management: Outcomes instead of projects, structured in a mindmap: https://docs.acorn.software/about-acorn/the-ontology-of-acorn

Same problem with VSCodium's AppImage (the error about libz.so.1). And yes, they're both just electron app so the differences haven't mattered yet. Acorn is a project management tool, I also tried Xplorer.

And here is the Acorn Beta.

Please check out the release, v0.5.1-alpha: https://github.com/h-be/acorn/releases/tag/v0.5.1-alpha
