It's a unique index then? And you're trying to read things ordered by

So all the values for an entire index will be in one row? That
doesn't sound good.
You really want to put each index [and each table] in its own CF, but
until we can do that dynamically (0.7) you could at least make the
index row keys a tuple of (indexid, indexvalue) and the column names

I don't know If that could play any role, but if ever you have

I noticed you turned Key caching off in your ColumnFamily declaration,
have you tried experimenting with this on and playing key caching
configuration? Also, have you looked at the JMX output for what
commands are pending execution? That is always helpful to me in
hunting down bottlenecks.

set up tables and indexes to store objects and have them indexed on
arbitrary properties. And we did a test implementation for
