I'm surprised that this hasn't been identified as a necessary feature yet. But odds are that at some point, this will be a required feature.
As you are aware, the following list typically represents the advantages of event sourcing. There needs to be some form of programmatic access that supports these activities.
- Auditing: Retrieve exactly what data looked like at any moment, enabling full traceability and regulatory compliance checks.
- Debugging: Roll back an application to investigate the state before, during, or after an incident to determine root cause.
- Historical Analysis: Examine trends, user behavior, or key metrics as they existed at different past moments, useful for analytics and business intelligence.
- Replaying Transactions: Reconstruct business processes or re-process data (for example, after correcting a bug) as they happened up to a specific point.
- Compliance and Legal: Supply evidence of change or access at a particular time for legal or regulatory requirements.
- Disaster Recovery: Recover a system to the last known good state after data corruption or unwanted changes.
