One of the most important parts of the Mattermost source code is the one responsible for accessing the Mattermost database: the store. Every single database access is handled by the store, so we needed to find a way to extend its functionality while introducing as little complexity as possible. This is the reason behind the current layered approach using struct embedding.

Today marks five years since the start of the Mattermost open source project! We reflected on this exciting journey and reminisced about our missteps along the way. We’ve had many laughs and wanted to share them with our community.

HiveMQ is an open source MQTT-compliant broker for enterprise-scale IoT environments that lets you reliably and securely transfer data between connected devices and downstream applications and services. With HiveMQ, you can provision horizontally scalable broker clusters in order to achieve maximum message throughput and prevent single points of failure.

Frequent logouts are a frustrating experience for users, especially on servers with short session lengths configured. In v5.24 and later, you can enable the configuration setting for extending session length with activity to automatically extend sessions and keep users logged in as long as they are active in their Mattermost apps.
