Namespace provides a variety of storage solutions that allow your instances to securely store and access required data. All storage solutions maximize data proximity to avoid network transfers and ensure high throughput.

​
Cache Volumes

Cache Volumes are local, NVME-backed storage that allows you to reuse cache artifacts from one instance in another. They offer very high read/write performance, require no remote file transfers and work well in high fanout scenarios.

​
Persistent Volumes

Persistent Volumes provide durable block storage that is guaranteed to persist across instance lifetimes. Data is automatically snapshotted on shutdown, and new volumes can be initialized from a specific snapshot.

​
Container Registry

nscr.io is a fully managed container registry built atop the same technology as our high-performance artifact storage. It seamlessly integrates with Namespace products and requires zero configuration to start using it.

​
Artifact Storage

Namespace maintains high-performance artifact storage, ideal for workflow artifacts. It is globally distributed, with transparent local caching. Artifact storage offers highly-available, high throughput object storage that is seamlessly integrated with the rest of Namespace. It is the backing technology behind our Bazel cache and Turborepo integration.

​
Secrets

You can store sensitive configuration data in your workspace by writing them to Namespace Secrets. When creating an instance, you can inject secrets directly into the environment.
