Are you spending too much time stitching together separate systems, adding immense complexity, and new points of failure? 🤔

Did you know there’s a way to avoid that?

During our latest webinar, @alejandro_du took a deep dive into MariaDB #AI RAG, a new component of MariaDB Enterprise Platform, designed to encapsulate the complete RAG lifecycle. 🔁

Catch all the action. https://t.co/BnXy3Kpito

Have you met #MariaDB Enterprise Manager? 👋

Part of MariaDB Enterprise Platform, Enterprise Manager is a native monitoring and management solution that reduces operational overhead and costs by leveraging a ready-to-use monitoring solution.

Developer Relations Engineer, @alejandro_du, demonstrates how to get started.

[MariaDB @mariadb]

This just in: #MariaDB Enterprise Platform has been named the WINNER of the 2026 @Data_awards for Data Management Platform of the Year! 👏

"MariaDB’s architecture is designed as a single, cohesive system – not a collection of loosely compatible parts – to ensure fast and reliable ingestion and querying of data across every use case,” said MariaDB CPO Vikas Mathur.

[MariaDB @mariadb]

Many enterprise DevOps teams are struggling to deploy frequently, increase test automation, and ensure reliable releases.

What can they learn from SaaS companies where developing and deploying software is part of their core operations?

#MariaDB’s developer relations engineer, @alejandro_du, shares his answer in @infoworld: https://t.co/ZWDJgkVFX2

[Alejandro Duarte @alejandro_du]

The layer I work on, and wear, most days.

"#MariaDB distance calculations already use inner product internally, there is no need to resort to hacks. Unfortunately, we keep getting these requests and even code contributions regularly."

🤔 Here's why MariaDB doesn't offer an "inner product" distance function 🧵

[Alejandro Duarte @alejandro_du]

"Inner product is not a proper distance [function] (as it does not have a minimum when a vector is compared to itself), and it is only used as a hack [...] in those #databases" 🧵
