How does data consistency work in immutable databases?

Can you explain how data consistency is maintained in immutable databases?

In immutable databases, data consistency is achieved by ensuring that once data is written, it cannot be altered. Instead, any updates create new versions of the data, preserving the original.

What are the benefits of using immutable databases for data consistency?

The benefits include enhanced data integrity, easier debugging, and improved audit trails since all changes are tracked as new entries.

Are there any challenges associated with immutable databases?

Yes, challenges include increased storage requirements due to multiple data versions and potential performance issues when querying large datasets.

How do immutable databases handle transactions?

Immutable databases often use techniques like event sourcing or versioning to manage transactions, ensuring that all changes are recorded in a consistent manner.
