So maybe this idea has been sent around before but I would like to
know what everyone thinks. We have a huge column family called bigdata
let's say 200 gb a node. We have used cass* as you would expect we
never read before writing and during our bulk loading we can get rates
like 2000 inserts per s

Maybe the ship on this has sailed, but I am a bit miffed on "create
table". CQL is going out of its way to make things so easy for people. But
if someone does not understand the concept of a column family making it
easy for them to design something that is an anti-pattern is odd to me.
As an admi
I have a github fork of hector that deals with the removed key and row
cache settings in the column family meta data. I needed this because it
helped me build hive 0.8 and c* in the same jvm. But it is useful because
older Hector clients have trouble talking to 1.1 if you try anything meta

I just see vnodes as a way to make the problem smaller and by making the
problem smaller the overall system is more agile. Aka rather then 1 node
streaming 100 gb the 4 nodes stream 25gb. Moves by hand are not so bad
because the take 1/4th the time.
The most simple vnode implementation is vmware.
Some work I did stores JSON blobs in columns. The question on JSON
type is how to sort it.

The issue with these super complex types is to do anything useful with
them you would either need scanners or co processors. As its stands
right now complex data like json is fairly opaque to Cassandra.

If you are using ~[na:1.6.0_14 you should upgrade to a later 1.6 JVM

As soon as you use the CLI to change the compaction strategy for a
column family Cassandra will consider all SSTables level 0 and being
level-ing them. With that much data, think hard before making the
change. You have to understand how level ed will work with your
workload.
