# Qdrant 2024 Roadmap

Hi!
This document is our plan for Qdrant development in 2024.
Previous year roadmap is available here:

* [Roadmap 2023](roadmap-2023.md)
* [Roadmap 2022](roadmap-2022.md)

Goals of the release:

* **Maintain easy upgrades** - we plan to keep backward compatibility for at least one minor version back (this stays the same in 2024).
  * That means that you can upgrade Qdrant without any downtime and without any changes in your client code within one minor version.
  * Storage should be compatible between any two consequent versions, so you can upgrade Qdrant with automatic data migration between consecutive versions.
* **Make serving easy on multi-billion scale** - Qdrant already can serve billions of vectors cheaply, using techniques as quantization. In the 2024 year, we plan to make it even easier to scale it.
  * Faster and more reliable replications
  * Out-of-the-box read-write segregation
  * Specialized nodes and multi-region deployments
* **Better ecosystem** - in 2023 we introduced [fastembed](https://github.com/qdrant/fastembed) to simplify embedding generation but keep it out of the core.
  In 2024 we plan to continue this trend: implement more advanced and specialized tools while keeping the core focused on the main use-case.
  * Advanced support for sparse vectors - we plan to make sparse vectors inference as fast and easy as the dense one.
  * Hybrid search out of the box with no overhead - something you can build with Qdrant today, but in a more convenient way.
  * Practical RAG - battle-tested RAG practices with production-grade implementation.
* **Various similarity search scenarios** - develop vector similarity beyond just kNN search.

## How to contribute

If you are a Qdrant user - Data Scientist, ML Engineer, or MLOps, the best contribution would be the feedback on your experience with Qdrant.
Let us know whenever you have a problem, face an unexpected behavior, or see a lack of documentation.
You can do it in any convenient way - create an [issue](https://github.com/qdrant/qdrant/issues), start a [discussion](https://github.com/qdrant/qdrant/discussions), or drop up a [message](https://discord.gg/tdtYvXjC4h).
If you use Qdrant or Metric Learning in your projects, we'd love to hear your story! Feel free to share articles and demos in our community.
