> StoreFile.java is trending to become a monolithic class, it's ~1800 lines. 
> Would it make sense to break out reader and writer (~500 lines each) into 
> separate files.
> We are doing so many different things in a single class: comparators, reader, 
> writer, other stuff; and it hurts readability a lot, to the point that just 
> reading through a piece of code require scrolling up and down to see which 
> level (reader/writer/base class level) it belongs to. These small-small 
> things really don't help while trying to understanding the code. There are 
> good reasons we don't do these often (affects existing patches, needs to be 
> done for all branches, etc). But this and a few other classes can really use 
> a single iteration of refactoring to make things a lot better.
