Windows, getting errors:

Yes. This is one of the things fixed for 1.0 in

Spolved - just used appropriate ant's targets to get jars built.

I found that there's no C library under Windows, and msvcrt does not provide
mlockall function, so currently there's no way to use JNA under Windows. That
way mmap is not a good idea?

We have done exactly as you describe (nested dicts etc) - works fine as long
as you are happy to read the whole lump of data, i.e. don't need to read at
a finer granularity. This approach can also save a lot of storage space as
you don't have the overhead of many small columns.
Some folks also wri
More of it, Cassandra 0.8.6 still leaves all commit logs under Windows.

I just read through the DataStax compression post (
http://www.datastax.com/dev/blog/whats-new-in-cassandra-1-0-compression).
My question is around good use cases for enabling compression. In my
scenario I have very wide rows with many thousands of columns where its
essentially time-series inform
What was the target you were using that didn't work?

mmap is supported by the JDK, jna is not required.

Is it worth a back-port or at least switch to asByteArray for 0.8.7? It's a
sizable amount of wasted network traffic and the fix seems pretty safe. (It's
working for me)

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

The full backport is beyond the scope of what I'm comfortable in a
stable release series, but the asByteArray fix sounds reasonable to
me. Can you create a ticket + patch?

Hey guys,
Are there any side-effects of increasing
the thrift_framed_transport_size_in_mb and thrift_max_message_length_in_mb
variables from their default values to something like 100mb?
Thanks!

I have a column family for my main data, and I have been using an additional
column family to store indexes to the data: row per index style.
I now want to be able to update a set of indexes by the field being indexed on.
To access that set, I can maintain meta indexes for each field, or I can

Really large messages are not encouraged because they will fragment
your heap quickly. Other than that, no.
