> h3. Background
> RowFile is the row-oriented binary file format of Tajo. Currently, RowFile does not support compression. 
> h3. Proposal
> The goal of this proposal is to implement block-based compression of RowFile. Requirements are follows.
> * The compression type should be configurable via TableMeta. 
> * The block size also should be configurable via Configuration. 
> * LZO, BZip2, GZip should be supported. (I recommend utilizing Hadoop's CompressionInputStream/CompressionOutputStream)
