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
