Hi, yuzhang.

What’s the encoding of the column that you query? The original intention of the code that
you mentioned is to find out the columns with inconsistent sequence before and after encoding.

主题: Re: Should I remove this check about compare the last and fetched

Sure, here is the code  at SortedIteratorMergerWithLimit.java:130. And the "Not sorted! last:
XXXXXX fetched: XXXXXXX" exception may happen when query some table contain Chinese value(or
messy code).
```

@Override
public E next() {
if (!nextFetched) {
throw new IllegalStateException("Should hasNext() before next()");
}

//TODO: remove this check when validated
if (last != null) {
if (comparator.compare(last, fetched) > 0)
throw new IllegalStateException("Not sorted! last: " + last + " fetched: " + fetched);
}

last = fetched;
nextFetched = false;

return fetched;
}

```

I not sure can understand your question cleanly. Can you give more
information about it, just like with a good sample.  Also you can forward
the code what you found and think that is happened!
