Adrien Grand commented on LUCENE-8739:
--------------------------------------

Hi [~wicked1099], force-merging wouldn't change anything: we still compress 
data into small chunks of ~48kB in order to be able to decompress as little as 
possible when reading a single stored document.

We don't like introducing options in the default codec because it makes 
backward compatibility too hard and prevents us from moving forward. Expert 
users can still create their own codec if they wish to.
