Hello Everybody,
I am trying to understand how disks are filled in cassandra.
If we run cassandra in a cluster of N (commodity) servers and each

Hi Jonathan,
That's me. I understand that it can be painful to update.
However I would say that a project of the size and popularity of

I don't suppose something like Doxygen could be made to work with xml

key: Paris, super column key: 2008.12.31.23.46.00, columns: (docid:109,

Writing your own JMX client is not that difficult.
The natural language to write JMX clients is Java, but if you prefer to
use your favourite language like Python or Ruby, there is a 'natural'
