Redis does not roll back transactions like relational databases do.
If you have a background of relational databases, the fact that Redis commands may fail during a transaction, but still Redis will execute the rest of the transaction rather than rolling back, may seem strange to you.
However, there are good opinions regarding this behavior:
Redis commands can fail only when called with the wrong syntax (and the problem is not detected during the command queue) or against keys containing the wrong data type: this means that from a practical point of view the failure command is the result of programming errors and some error that will most likely be detected during development, rather than in production.
Redis is internally simplified and faster because it does not need the ability to roll back.
