Column names are stored at every row since this is nosql key value store. If you are storing a schema based data, it is highly inefficient.
More data fits into memstore => less flushing
Less flushing => less hfiles
less hfiles => lesser compaction work and faster scan
small column names means more data fits into one block
More data fits into memory, faster scan.
