How do Firestore transactions work?

Can you explain how Firestore transactions work?

Sure! Firestore transactions allow you to perform multiple read and write operations atomically. This means that either all operations succeed, or none do.

What happens if a transaction fails?

If a transaction fails, Firestore automatically rolls back all changes made during that transaction, ensuring data consistency.

How do I implement a transaction in my code?

You can use the runTransaction method provided by Firestore. It takes a function that performs the read and write operations.

Are there any limitations to Firestore transactions?

Yes, transactions can only read and write to a maximum of 500 documents at a time.
