worth choosing the shortest possible column names/keys?

[TuX RaceR]

Hello Hbase Users List,

In the SQL world, you can choose column names that clearly describe a 
field (i.e. long names)
I believe it is different in Hbase.
Is it worth choosing the shortest possible column names and keys
ie:
c1234:fn:John,ln:Doe

intead of

customer_1234:FirstName:John,LastName:Doe


?
Will I save a lot of space (especially if I have many small columns)?

Thanks
