> Wasn't expecting there to be much of a difference across these - I'm guessing the other types may be misreporting their benchmark since they don't take into account the proper sizing of an all null array? Well, fixed-width types such as Int or Bool types don't need special care: for them, a null entry consumes the same amount of space as a non-null entry. String types are variable-width, though. The differences look believable to me (different algorithms are used), though I admit the String numbers are better than I expected. -- This is an automated message from the Apache Git Service.
