> DruidScanQueryRecordReader gets a compacted List<Object> from druid. It then converts
that list into a Map<String,Object> as DruidWritable where key is the column name. 
> At the second stage DruidSerde takes this DruidWritable and creates a List out out of
the map again. We can avoid the map creation part by reading the list sent by druid directly
in the DruidSerde.deserialize() method.
