What are streams
A stream is simply a sequence of data points in time, i.e. an append only log. This is semantically equivalent to topics in traditional pub/sub networks.
- Sequence of data points in time
- Any kind of real-time data can be stored in it
- The data will always be retrieved in the correct order
- Identified by unique stream IDs
Let's say you have a temperature measurement device that publishes the temperature of your house every second. Then this is how your stream would look like:
Your stream would grow over time and you can add more colums/data fields to your timestamp.
