Using wide rows for indexing is extremely common.  I was wondering if we co=
uld get some type of command like so for index rows

Remove <value1>.<pkX> AND Add <value2>.<pkX> such that if <value1>.<pkX> is=
 NOT found, the whole row will be scanned for <ANYvalue>.<pkX> and remove t=
hat value instead.  This would rock for all those people using wide rows as=
 indices on a RF=3D3 with QUOROM writes and reads as the index would always=
 be consistent as well.

The above situation can occur frequently in some systems and it would just =
be nice for it not to happen with QUOROM and RF=3D3 is all.

Maybe I should just file a ticket and if it ever picks up enough votes, the=
 community might consider implementing it?

Thoughts?
