Also, this is pretty subjective, so I can't say for sure until it finishes, but
this seems to be running *much* slower after setting the heap size and setting
up JNA.

I'm using Cassandra 0.7.5, and uploading about 200 GB of data total (20 GB
unique data), to a cluster of 10 servers. I'm using batch_mutate, and breaking
the data up into chunks of about 10k records. Each record is about 5KB, so a
total of about 50MB per batch. When I upload a smaller 2 GB da
th this guarantee.

I've been experimenting with the consistency model of Cassandra, and I found
something that seems a bit unexpected. In my experiment, I have 2 processes, a
reader and a writer, each accessing a Cassandra cluster with a replication
factor greater than 1. In addition, sometimes I generate backgr
