## What's an event streaming store?

If you think of an "event" like a frame in a movie—a small package on a

timeline—an event streaming store is a database designed to record these frames

in strict order, append-only, so they can be replayed or reacted to later.

For example, you might append a frame every time a message is

[posted in a specific Discord channel](examples/discord-bot). You can then

[`.cat`](https://cablehead.github.io/xs/reference/xs-nu/#cat) the stream to

review all captured messages, and—if you're in a

[Nushell](https://www.nushell.sh) session—use pipelines to filter, aggregate, or

process them with a CLI tool.

## Quick Start

See the

[installation guide](https://cablehead.github.io/xs/getting-started/installation/)

to get started.

## Features

- **Reactive Workflows**: Build handlers that automatically respond to events as

  they flow through the stream

- **CLI Integration**: Turn any command-line tool into a streaming component

  with generators

- **Nushell Native**: First-class integration with Nushell for powerful data

  processing pipelines

- **Real-time Streaming**: Subscribe to live event feeds and build responsive

  applications

- **Content Addressable**: Efficient storage and deduplication of large payloads

- **Local-first**: Your data stays on your machine, no cloud dependencies

  required
