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. You can then .cat the stream to review all captured messages, and—if you're in a Nushell session—use pipelines to filter, aggregate, or process them with a CLI tool.
