   @xiarixiaoyao this is a good question, something I have been thinking about 
too. The idea is to build a layer that will help in integrating column stats 
index with all java based engines like presto, trino and hive. This lays the 
foundation, since we need something like ranges so as to be able to filter the 
files using min and max values. Few classes here are actually inspired from 
those present in presto, but they are not exactly similar.
   We can end up writing this logic in presto, but then a similar work will 
have to be done for trino as well.
   
   Although since this is just the beginning of this work, I am open to hear 
others' thoughts on this.
