# Durable Streams - Forking

Branch a stream from any point and read it as one

## What this does

Sometimes you want a variant of a stream that starts from a particular point rather than a whole new one from scratch. This covers making that branch and then reading it, where the inherited part and the new part come back stitched together. Reach for it when you are forking or branching a stream you already have.

### Top 3 things it does for you

- Branch a stream from a chosen point
- Read a fork and its source together as a single stream
- Understand what a fork inherits from its source

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Durable Streams - Forking

This is about creating and using forked streams. You fork a source stream at a specific offset, and reads then transparently stitch together the inherited data and the fork's own data.

It covers the shape of the work around that: creating a fork, the fresh handle pattern, what a fork inherits in terms of expiry and content type, and the deletion lifecycle. Load it when you are forking, branching, or creating a variant of an existing stream.
