Editor to share with you what are the transaction commands in Redis, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Transaction 1.1 MULTI and EXEC commands

Send MULTI commands to declare the transaction; EXEC executes the transaction

Redis does not support transaction rollback

Monitor a key value and, if modified, prevent subsequent transactions from executing. Only defensive in nature.
