How can I handle errors in Redis Lua scripting?

How can I handle errors in Redis Lua scripting?

In Redis Lua scripting, you can handle errors using the error() function. This allows you to throw an error when a specific condition is met.

Can you give me an example of using the error function?

Sure! You can use it like this: if not myCondition then error('Condition failed!') end. This will stop the script and return the error message.

What happens if I don't handle errors?

If you don't handle errors, the script will fail, and Redis will return an error message without executing any further commands.

Are there best practices for error handling in Lua scripts?

Yes, it's best to validate inputs, use descriptive error messages, and consider using pcall for protected calls to catch errors gracefully.
