For example:
user['lee'] = {
'name': 'lee',
'age'; '21',
'girls': ['java', 'actionscript', 'python'],
}
how to store above in Apache Cassndra ?

A way to read all the db without having an OOM is to limit the amount
of rows to be returned, and to iterate over the query, the starting
key being the last returned key. Note that doing that way the first
key of the next iteration is the same as the last key of the preivous
iteration.

Specifically are all the columns placed on the same node? What about super

Hi all,
this tells us to stop and start Cassandra ...
I hope we are not asked to stop whole cluster ... Can we proceed node
after node ?
( But how cluster could handle different config.xml files ?)

I'm running a test to write 30 million columns (700bytes each) to Cassandra:
the process ran smoothly for about 20mil then the heap usage suddenly jumped
from 2GB to 3GB which is the up limit of JVM, --from this point Cassandra
will freeze for long time (terrible latency, no response to nodetool
Hullo.
Think I got a bug in Cassandra. Do you also think it's a bug?
It should be noted that I experience this bug when using cassandra through
thrift's php api (the low-level one generated by thrift, not some high-level
from the cassandra wiki).
It happens when i insert a supercolumn (with a
