# Feature Support Matrix

Some of mirrord's advanced features - DB Branching, Queue Splitting, Preview Environments, and Multi-cluster - work across a range of platforms and infrastructure setups. Support levels vary by platform. The table below shows the current status for each combination.

#### The columns reflect the different contexts in which a feature can be used:

* Preview Env: using the feature inside a [preview environment](https://github.com/metalbear-co/docs/blob/main/docs/reference/use-cases/preview-environments.md). Each developer or agent gets an isolated slice of the dependency - for example, their own queue partition or database branch — within a shared staging cluster, without affecting others.
* Multi-cluster: using the feature across [multiple clusters](https://github.com/metalbear-co/docs/blob/main/docs/reference/using-mirrord/multi-cluster.md). Traffic, queue messages, or database connections are routed across cluster boundaries, useful when your infrastructure spans more than one cluster.
* mirrord up: using the feature when running multiple services together via [mirrord up](https://github.com/metalbear-co/docs/blob/main/docs/reference/using-mirrord/multiple-concurrent-sessions.md). Similar to how `docker compose` orchestrates containers, mirrord up lets you define and launch several interdependent microservices in a single `mirrord-up` file, managing their lifecycle as a group.
