1ms per add operation is the general order of magnitude I have seen with my tests.
I've got a 4 node cluster (ec2 m1.large instances, replication = 3)
that has one primary counter type column family, that has one column
in the family. There are millions of rows. Each operation consists of
doing a batch_insert through pycassa, which increments ~17k keys. A
majority of these keys are new in each batch.
Each operation is taking up to 15 seconds. For our system this is a
Does anyone know if this write speed is expected?
Thanks in advance,
