> I ran some TPCH(30) queries locally using orc/snap/block format. The profile counter of CollectionItemsRead seems weird for me:
> {code:java}
> - CollectionItemsRead: -1679471728382351781 (-1679471728382351781) {code}
> It could also be super large positive values, e.g.
> {code:java}
> - CollectionItemsRead: 1296851974.72B (1296851974721369461) {code}
