IMHO, Tanuki and the like are fabulous in a Windows environment (e.g., to
install something as a "Service"), but on a *nix, you're better off to just
come up with your own variant of the standard shell script and hook it into the
OS lifecycle in the usual way.

Hi, Brian --
A little late to reply, but I'm slowly catching up.
You're going to be better off, IMHO, to pull the data out of Cassandra with a
tool like Pig (probably with a bit of aggregation and filtering) and then
operate on it in R as a static delimited file. If you need additional

I didn't find it necessary. I implemented a simple embedding wrapper for
Cassandra so that it could be started as part of a web application lif
Lucene trades on (32-bit) ints internally, so I expect you're just seeing a
projection of that limitation.

You should make sure that your directions and interval endpoints are chosen
correctly. I recall the semantics of the call being like an old-school for
with the descending flag as a step of +1 or -1.

FWIW, I'm seeing similar issues on a cluster. Three nodes, Cassandra 0.6.1,
SUN JDK 1.6.0_b20. I will try to get some heap dumps to see what's building up.
I've seen this sort of issue in systems that make heavy use of
java.util.concurrent queues/executors, e.g.:

We went through this with Ode w.r.t. Hibernate. Note that Ode still ships with
Hibernate support there, just not with Hibernate libraries in the distribution
or with a strong dependence on Hibernate.
So, if you made Trove maps optional and provided an adapter, you'd be OK. You

The answer is misconception; I interpreted the behavior of get_slice to be
columns between X and Y, in ascending or descending depending on the "reversed"
flag, but it's a little different
start = X, end = Y, reversed =
I have a column family the column names are ISO dates, e.g., "20100405" or
"20100331", and the comparison is set to UTF8String. I have a unit test that
spins up a Cassandra instance, inserts a few records, and then tries to a
reverse traversal of a row by querying with an upper bound of initi
