   Hi, can we do more experiments about this encoding? The user guide said the zigzag is good for numbers with small absolute value. I think we need to know how small the numbers are. To be specifically, I think we can tell users if their data is smaller than the specific value, using zigzag is better. :)
   
   Besides, can we compare this encoding with PLAIN? I heard PLAIN is even better than RLE because we are actually using varInt for PLAIN type…
