Review Comment:
```suggestion
ImmutableSet<Column> selectIndexColumns = ImmutableSet.copyOf(
getTable().getIndexIdToMeta().get(indexId).getSchema());
return slots.stream()
.filter(slot -> ((SlotReference)
slot).getColumn().isPresent()
&& selectIndexColumns.contains(((SlotReference)
slot).getColumn().get()))
.collect(ImmutableList.toImmutableList());
