i would advise not to use a language specific storage format, you might
regret it later on if you want to add an application to your system that is
written in anything else than python. i mean python is great, but it is not
necessary the right tool for every job
look at thrift/protobuf/avro/bson/j
o and them i am by
accident using the wrong application. once applications are aware of their
home dir all i have to do is "ln -s /usr/lib/cassandra-0.7/bin/nodetool
/usr/sbin/nodetool-0.7" and then i can use it without risk of confusion.

i have an existing cassandra instance on my machine, it came with brisk and
lives in /usr/share/brisk/cassandra. it also created /usr/share/cassandra/
cassandra.in.sh
now i wanted to run another instance of cassandra (i needed a 0.7 version
for compatibility reasons), so i downloaded it from apach

I would like to do a get_range_slices for all keys (which are strings) that
start with the same substring x (for example "com.google"). How do I do that?
start_key = x abd end_key = x doesn't seem to do the job...
thanks koert
Cassandra keys and values are just bytes. My values range from simple doubles
to complex objects so I need to serialize them with something like avro, thrift
or protobuf.
Since I am working in a test environment and casssandra is moving to avro I
decided to use the avro protocol to communicate
right in line with how much faster I would expect Java
to be than pure Python.

While bootstrapping a new node, the existing node that is supposed to provide
the data throws an error, and the bootstrapping hangs. The log from the
existing node is below. Both nodes have little memory (only 2 Gig, windows
machines). I used default configurations (Cassandra 0.7). Any suggestio
hat helps.

Hello All,
I am testing Cassandra 0.7 with the Avro api on a single machine as a financial
time series server, so my setup looks something like this:
keyspace = timeseries, column family = tickdata, key = ticker, super column =
field (price, volume, high, low), column = timestamp.
So a single v
