Thanks, that made things better by about 30%. Unfortunately for me that's still
unacceptable... :-(
I feel like I'm doing something wrong with avro (see my original post). Was
anyone able to make it work?

One thing you should try is to make thrift use

Hi,
I'm attempting to use avro to talk to cassandra because the ruby thrift
client's read performance is pretty bad (I measured 4x slower than java).
However, I run into a problem when calling multiget_slice.
The server gives a KeyspaceNotDefinedException because
clientState.getKeyspace() retur
That looks like an error thrown from CFMetaData, telling you it's not possible to change a Standard CF to a Super CF. Which seems logical to me, how would it move the data from a standard CF to a super CF? You'll need to create a new Super CF and migrate the data manually. AaronOn 29 Sep, 2010,at

what about modifying the actual column family configuration values,

Peter - my apologies for the slow response - we had
to divert down a 'Plan B' approach last week involving
MySQL, memcache, redis and various other uglies.
