-------------------------------------------------------------------
bq. I'd like to call Matt's protocol (plus framing and a version) "streaming
v2".
My main concern is that we have a single protocol for all streaming. Less
concerned about which protocol that is, although my impression is that it's
easier to do bulk load w/ existing (tested and debugged!) streaming, than to
make "streaming v2" backwards compatible w/ the existing one.
On the other hand, I don't think it's *strictly* necessary to require streaming
compatibility since a cluster can run fine without it for a few days while
doing a rolling upgrade. (Although it does make the "upgrade a single node,
wait for a week to see how it does" approach less viable.)

> Currently bulk loading into Cassandra is a black art. People are either
> directed to just do it responsibly with thrift or a higher level client, or
> they have to explore the contrib/bmt example -
> http://wiki.apache.org/cassandra/BinaryMemtable That contrib module requires
> delving into the code to find out how it works and then applying it to the
> given problem. Using either method, the user also needs to keep in mind that
> overloading the cluster is possible - which will hopefully be addressed in
> CASSANDRA-685
> This improvement would be to create a contrib module or set of documents
> dealing with bulk loading. Perhaps it could include code in the Core to make
> it more pluggable for external clients of different types.
> It is just that this is something that many that are new to Cassandra need to
> do - bulk load their data into Cassandra.
