Hi, Yes and no. No, because as a table can have millions of columns and these columns can be different for every row, the only way to get all the columns is to scan the whole table. Yes, because if you scan the table you can have the columns names. See Result#getMap: it's organized by family --> qualifier --> version --> value And yes, because you can get the column families from the HTableDescriptor.
