We are pleased to announce the release of the latest minor version of ReductStore, 1.10.0. ReductStore is a time series database designed for storing and managing large amounts of blob data.

What's new in 1.10.0?​

ReductStore v1.10.0 introduces new query and replication parameters that can downsample data when querying or replicating to another database. In addition, we have optimized the operation of the storage and replication engines, which should improve the overall performance of the database.

A year ago, we migrated ReductStore, time series database for unstructured data, from C++ to Rust. Now, reflecting on that decision after a year, it's clear that it was the right move, yielding the following benefits:

• Fewer bugs related to memory management, move semantics, and threading
• Easier codebase porting to MacOS and Windows
• Better dependency management with Cargo compared to what we had with C++

Today, I'm pleased to announce that we've rewritten the CLI client from Python to Rust. Our primary motivation was distribution. Although Python is one of the most widely used programming languages, we don't want to require users to install an interpreter to use our tools, and standalone installers are too bulky for us. With Rust, we can build compact and blazingly fast executable binaries for most popular platforms.

What’s New in 1.9.0?​

This release, version 1.9.0, introduces several key improvements and features to enhance the overall performance and user experience. These updates include optimizations for disk space management, the inclusion of replication support in the Web Console, and the provision of license information in the HTTP API.

What's New in ReductStore v1.8.0​

In this release, we're introducing a crucial feature for any database - data replication. Now, you can create a server-side task that "subscribes" to new records written to a bucket and forwards them to another bucket. This bucket can be located on the same instance or a remote one. Since all databases implement replication differently based on their specializations, let's examine how ReductStore tackles this.

What's new in 1.7.0?​

ReductStore v1.7.0 introduces two new features that make it easier to provision resources and write data in batches, which can improve your performance and efficiency when using ReductStore for edge computing and AI applications.

Business Source License (BUSL-1.1)​

We have updated the ReductStore license to the Business Source License (BUSL-1.1). This license permits free usage of the database for development, research, and testing purposes. Furthermore, it can be used in a production environment for free, provided that the Aggregate Financial Capacity of the company is less than $2,000,000 for the previous year. For additional information, please refer to here.

We believe that the new license strikes a good balance between freedom and revenue generation. This balance is necessary to maintain and improve our technology, and to bring benefits to its users.

Hello everyone,

I'm happy to announce that the next minor version of ReductStore has been released. For the last month, we worked hard to improve the user experience when querying data from the database. And in this release, we deliver two important features:

• Batching multiple records into an HTTP response for read operations
• Reading only meta information about a record without its body.

Let me show you how it works in detail and how you can use it.

I am happy to announce that we have completed the migration from C++ to Rust, and have released a stable version (v1.4.0) that is entirely written in Rust. 🤩

It was not an easy journey. After six weeks of coding, we encountered numerous regressions and changes in behavior. I needed to release two alpha and two beta versions with production testing to clean up the database. Now, it is finally ready!

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.
