All or Nothing: DuckDB Transaction Guarantee
Problem:
Data operations can fail partway through, leaving databases in inconsistent states.
Money transfers, inventory updates, and other critical operations need guaranteed atomicity.
Solution:
DuckDB uses ACID transactions to maintain data integrity. Operations either complete fully or roll back completely using BEGIN, COMMIT, and ROLLBACK commands.
Why ACID transactions matter:
- Atomicity: prevents half-completed operations
- Consistency: maintains database integrity rules
- Isolation: stops concurrent operations from conflicting
- Durability: ensures committed data survives system failures
