Which node will run a SCRIPT in cluster mode with multiple shards?

[bibicu123]

I am trying to understand how go-redis will run a script with cluster enabled and multiple shards?
Which node will choose to run the script on ?

Let's assume a script that reads a key A and writes another key B based on the value of A. To keep things simple, both keys hash to the same slot.

Is go-redis smart enough to parse the keys and run it on corresponding node ?

Yes, go-redis will choose a shard based on the first key in the argument list.
