I've done some more testing with a simple table on a pseudo-distributed system
(my laptop). Below is the test script with the various tests' outputs. I
guess where I'm really getting confused is when I query for info:lame =
Washington and want the info:fname column returned, why are all fname'

I take it you made SingleColumnValueFilter do the right thing first?

I think this fits what I'm trying to do, but have been having a heck of a
time with it.
I'm using a SingleColumnValueFilter to get rows who's cf:qual have a given
value, but would just like the key, no values. If I add that filter to a
filterList with a KeyOnlyFilter.new, I get nothing if KeyOnly

sounds like he would be better off writing
Yes i need the column names. Writing to 2 table will have too much payload.
I have very strict requirement on latency/throughput having additional
round trip just for getting the meta data of a row is too much.
Similarly to

Hi
I would like to know if it is possible to retrieve the columns name and not
the whole content of rows.
The reason for such request is that the columns store high volumn of data
(2K) each (and i store 900 columns per key).
Retrieving the whole row and not the "Description/Metadata" of the row is
