Schema with 5K columns
In this schema, only 100 random columns are filled with random 15 chars. Rest are nulls.
Data size is 6X larger with encoded columns scheme compare to non-encoded. That is 12GB/1M rows encoded vs ~2GB/1M rows non-encoded.
When compressed GZ, size with encoded column scheme is still 35% higher.
