Merged through d692cdfdff611c848461daf80b4ee0f419a73956, thanks! btw, what is for it's used in Dropbox? Is it the same petabyte storage engine or now it's not the only internal Rust project?
lol, I take it you've been chatting with Jamie :)
It's a new project for storing some timeseries data. Still very experimental, but so far so good!
Nope, he mentioned that petabyte engine on reddit, but it was pretty general, without any specific details.
It would be exciting to have a post in engineering blog regarding any of internal Rust projects as there is not that much info about Rust in the wild and especially Rust at scale. /cc @jamwt
Hey @vhbit,
Yeah, @frew's project is a completely separate thing. So Dropbox now has two major projects using rust:
Yep, I've got that those are different projects, but the question is if any of you has plans to write a detailed post for Dropbox engineering blog?

- Components of our multiple-exabyte main block storage system (i.e. where your files are kept)--the original project my team started up on back toward the start of 2015.
- A new storage engine for Dropbox's production analytics, @frew https://github.com/frew 's new project. This is the one using lmdb.

Ah, I see. We will eventually, but there are no immediate plans.

These methods are all thin wrappers around NativeTransaction methods that use dynamic dispatch so monomorphizing is probably a pessimization anyhow, and this lets these functions be called with dynamic dispatch (in our case we'd like to call the function with one of a variety of ToMdbValue concrete implementations, determined at runtime).
