What is the difference between Redis transactions and pipelines?

Redis transactions allow you to execute a series of commands as a single atomic operation, ensuring that either all commands succeed or none do. In contrast, pipelines allow you to send multiple commands to the server without waiting for the responses, improving performance but without atomicity.

Can you give me an example of when to use transactions?

Sure! Use transactions when you need to ensure data integrity, like transferring funds between accounts. You want both the debit and credit operations to succeed or fail together.

And when should I use pipelines instead?

Pipelines are great for scenarios where you need to execute many read operations quickly, like fetching data for a dashboard. They reduce the round-trip time by sending multiple commands at once.

Are there any limitations to using transactions?

Yes, transactions in Redis can only be used with commands that are supported in a transaction context, and they can introduce some overhead due to the locking mechanism.
