   In columnar database world, encoding is commonly referred to column level 
compression techniques which play nice with columnar query execution - 
dictionary encoding, RLE, delta where the true benefit is that query processing 
can happen on compressed columnar data (e.g dictionary encoding)
   
   The purpose of this issue is to not add any new column level encoding. I was 
thinking of having a separate issue to enhance column level encoding support 
with RLE, DELTA, PFORDELTA etc.
   
   This issue is for supporting additional data compression codecs for raw data 
which are currently snappy compressed
