Kills the currently executing Lua script, assuming no write operation was yet performed by the script.
This command is mainly useful to kill a script that is running for too much time(for instance because it entered an infinite loop because of a bug). The script will be killed and the client currently blocked into EVAL will see the command returning with an error.
If the script already performed write operations it can not be killed in this way because it would violate Lua script atomicity contract. In such a case only
SHUTDOWN NOSAVE is able to kill the script, killing the Redis process in an hard way preventing it to persist with half-written information.
Please refer to the EVAL documentation for detailed information about Redis Lua scripting.
