> Immutable column encoding with offset data is highly compressible, in test with various schemas, space saving ranges from 1.5X to 3X whereas FAST_DIFF encoding has not any significant impact as expected. 
> Enabling compression would lead to better performance for disk I/O bound queries. The amount of space saving depends on sparsity, number of columns and data shape.
