> Enable schema-aware compression codecs which can perform type-specific compression on a per-column basis. I see this as in three-parts
> 1. Add interfaces for the rcfile to communicate column information to the codec
> 2. Add an "uber compressor" which can perform column-specific compression on a per-block basis. Initially, this can be config driven, but we can go for a dynamic implementation later.
> 3. A bunch of type-specific compressors
> This jira is for the first part of the effort.
