How do I handle errors in Redis transactions?

In Redis, you can handle errors in transactions by using the WATCH command to monitor keys and checking for errors after EXEC.

What happens if a key is modified during a transaction?

If a key is modified after WATCH and before EXEC, the transaction will fail, and you'll receive a nil response.

Can I retry the transaction after a failure?

Yes, you can retry the transaction by reissuing the WATCH command and attempting the transaction again.

Are there any best practices for using transactions in Redis?

It's best to keep transactions short, avoid long-running operations, and handle potential errors gracefully.
