Review Comment:
Technically, `pushedLimit` should never be 0 because Spark converts a limit
of 0 to an empty table scan. I have changed the initial value of `pushedLimit`
to -1 to ensure that it is never 0.
I have modified the code accordingly. Is this better?
```
public boolean hasNext() {
long numToRead =
(pushedLimit == -1 || pushedLimit >= totalValues) ? totalValues :
pushedLimit;
return valuesRead < numToRead;
}
```
