> Looking at PrefixFilter, I have noticed that it doesn't use the SEEK_NEXT_USING_HINT mechanism.
> AFAICT, we could safely set the the prefix as a next row hint, which could be a huge performance win.
> Of course, ideally the user would set the scan startRow to the prefix, which avoids the problem, if the user doesn't, then we effectively do a full scan until the prefix is reached.
