+ * function: pointer to the C function implementing the command.
+ * arity: number of arguments, it is possible to use -N to say >= N
+ * sflags: command flags as string. See below for a table of flags.
+ * flags: flags as bitmask. Computed by Redis using the 'sflags' field.
+ * get_keys_proc: an optional function to get key arguments from a command.
+ *                This is only used when the following three fields are not
+ *                enough to specify what arguments are keys.
+ * first_key_index: first argument that is a key
+ * last_key_index: last argument that is a key
+ * key_step: step to get all the keys from first to last argument. For instance
+ *           in MSET the step is two since arguments are key,val,key,val,...
+ * microseconds: microseconds of total execution time for this command.
+ * calls: total number of calls of this command.

+ * always be set to zero.
