Message Store
Archive messages as they flow — for replay, analysis, and debugging.
Intent & Description
Real-world Use Case
Event replay after data corruption — database corruption detected on Tuesday. Message Store contains all events from the past 7 days. Ops team replays all events from Monday midnight, rebuilding the state of the system cleanly. No data loss.

📌 TL;DR
Message Store = a DVR for your message pipeline. Records everything, enables replay. Essential for debugging, disaster recovery, and compliance. Watch the storage bill and handle PII carefully.
Advantages
- Complete message visibility for debugging and post-mortem analysis
- Enables event replay for disaster recovery or state reconstruction
- Supports compliance requirements (message retention mandates)
- Pairs with Wire Tap for non-invasive message capture
Disadvantages
- Storage requirements grow continuously — needs retention policies and archival
- Storing all messages at high throughput is expensive (compute + storage)
- PII in messages must be handled carefully — store may need encryption and access control
- Message store is itself a critical operational dependency
