Siying Dong 9fad3e21eb Merging iterator to avoid child iterator reseek for some cases (#5286) ... Summary: When reseek happens in merging iterator, reseeking a child iterator can be avoided if: (1) the iterator represents imutable data (2) reseek() to a larger key than the current key (3) the current key of the child iterator is larger than the seek key because it is guaranteed that the result will fall into the same position. This optimization will be useful for use cases where users keep seeking to keys nearby in ascending order.
