You can also use slice a range of columns for a row , e.g. first 100 columns after column "aaaa". 

What client are you using ?

but I'm afraid it's not a graceful means if there are billion columns in a row.

just use "get" Thrift method where "super_column" and "column"
attributes in ColumnPath structure are empty. Yes, it returns both
column names and values but I'm afraid there is no Thrift-way how to
get column names only.
