Potential Side Effects of Reusing Iterators vs. Creating New Instances?

[marks-yag]

In my application scenario, I heavily rely on Iterator.SeekForPrev() for data retrieval. I've found that reusing the Iterator (via thread-local storage and performing Refresh before and after each use) improves performance by 10% to 80% compared to creating a new Iterator object each time.

I would like to ask what additional side effects might arise from reusing the Iterator handle compared to creating a new one each time?

Thand you!
