Your data pipelines fail. You lose state. You struggle to recover.
Event sourcing fixes this. It treats data as a sequence of events.
Here is the setup:
- Event Store: An append-only log. It records every change.
- Streaming SQL: It transforms data in real time.
- Read Models: It saves the final state for fast queries.
Why use this?
- Replayability: Run events again to rebuild state.
- Reliability: Checkpoints let you resume after a crash.
- Speed: Get low latency updates.
Follow these steps:
- Define your event model.
- Build a writer for your event log.
- Set up streaming queries for your metrics.
- Add a checkpoint system.
- Test with a full replay.
Stop guessing your state. Start recording it.
