# Durable Streams - StreamDB

A database that updates itself from the stream behind it

## What this does

You want your app's data to stay current as new events arrive, without wiring the refresh logic yourself. This is a database that sits on top of a stream and reacts to it, with collections you can query and changes that can show up immediately while they are being confirmed. Reach for it when your interface needs to follow live data.

### Top 3 things it does for you

- Set up a database backed by a stream
- Query collections with familiar operators
- Show a change straight away and confirm it after

## About Durable Streams - StreamDB

This is a stream-backed reactive database. You create it with a schema and stream options, initialize lazily when you are ready, and read through collections you can query with re-exported operators for comparison, combination, counting, and aggregation.

It also covers writing and lifecycle: optimistic actions with a mutation handler, awaiting a transaction ID to confirm a write, the control events that mark snapshots and resets, and closing the database to clean up.
