    @omalley  Thank you for the patch and initial performance result. The result looks very promising. With current result, looks like different encoding (FPC V1, FPC V2 and split) fits for different data set while split encoding is more compression friendly.  Not sure whether we can implement it as what RLE did. Dynamically determine the encoding based on the characteristics of data set. Any thoughts on this?
