 Cluster mode has limited support for lua scripting.
 
-The following commands are supported, with caveats: - ``EVAL`` and
-``EVALSHA``: The command is sent to the relevant node, depending on the
-keys (i.e., in ``EVAL "<script>" num_keys key_1 ... key_n ...``). The
-keys *must* all be on the same node. If the script requires 0 keys, *the
-command is sent to a random (primary) node*. - ``SCRIPT EXISTS``: The
-command is sent to all primaries. The result is a list of booleans
-corresponding to the input SHA hashes. Each boolean is an AND of “does
-the script exist on each node?”. In other words, each boolean is True
-iff the script exists on all nodes. - ``SCRIPT FLUSH``: The command is
-sent to all primaries. The result is a bool AND over all nodes’
-responses. - ``SCRIPT LOAD``: The command is sent to all primaries. The
-result is the SHA1 digest.
