The MQTT protocol is an easy way to connect different data sources to applications. This makes it very popular for IoT (Internet of Things) applications. Some MQTT brokers can store messages for a while, even when the MQTT client is offline. However, sometimes you need to keep this data for a longer period of time. In these cases it's a good idea to use a time series database.

There are many databases available for storing MQTT data, but if you need to store a history of images, vibration sensor data or protobuf messages, you might want to use ReductStore. This database is designed to store a lot of blob data and works well with IoT and edge computing.

ReductStore has client SDKs (software development kits) for many programming languages. This means you can easily use it in your existing system. For this example, we'll use the Rust SDK from ReductStore.

Let's build a simple MQTT application to see how it all works.

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.
