I previously wrote about my plan to rewrite ReductStore in Rust. I am happy to announce that the migration is now complete. It was a very interesting 6 weeks for me, and I would like to share my experience with you.

Project Design before Migration​

I wrote ReductStore in C++20, utilizing coroutines and ranges.

For the HTTP frontend, I used uWebSockets as an HTTP server and its event loop for coroutines.

The storage engine was implemented from scratch.

I used Protobuf as a JSON and binary serializer in both the HTTP frontend and the storage engine. Many of the structures were shared between the two.

I managed dependencies with Conan and used CMake as a build system.

Codebase about 20k lines with unit tests.

About Me​

I have been developing in C++ and Python for about five years. Mostly, I write services for data acquisition, processing, and storage. I like OOP, design patterns, and my C++ smells Java. However, I avoid using exceptions and follow the RAII approach.

In Rust, I have only written the "Hello, World" example.

I work on the project in my spare time 10-20 hours a week.

Migration​

Initially, I planned to use the cxx.rs library and rewrite the project in small steps by wrapping Rust code and integrating it into C++.

[SPOILER] I wasn't able to handle this...

Initially, I chose to use C++ for the early editions of ReductStore because of my experience with the language. This allowed me to quickly create a functional time series database for binary data. However, as our platform expanded to include Windows and MacOS, I found myself struggling to manage the C++ infrastructure as the codebase grew. This made it difficult for me to focus on enhancing the product's functionality and unique features, as I had to ensure compatibility across multiple platforms while managing numerous dependencies.

By making ReductStore available on the Snap Store, users can now easily install and manage ReductStore on various Linux distributions.

Snap is a universal package manager developed by Canonical, the company behind Ubuntu Linux. It allows developers to package their applications and dependencies into a single package that can be installed on any Linux distribution that supports snap, without worrying about different packaging formats and dependency conflicts.
