Example code using C# below:
Collections.Generic.List results;
SlicePredicate predicate;
ColumnParent cp;
// Create Slice
predicate = new SlicePredicate()
{
Slice_range = new SliceRange()
{
Start = _utf8.GetBytes(""),
Finish = _utf8.GetBytes(""),
Count = 100,
Reversed = false
Have you looked at get_slice or multiget_slice (
http://wiki.apache.org/cassandra/API) to see if those will fit your needs?
I would expect the slice_range property of the SlicePredicate might get you
started.

I understand the technical aspects of how that should work; however, before
I begin that, does anyone have any suggestions or tips?

I am working with 0.7.0-beta1 (distribution from bin on website)
First, am I correct in that since beta1 keys are now bytes instead of
strings?
Second, should there be additional data before the key value that I specify
(read below for explaination)?
I am attempting to perform a batch mutation w
Just a tip for evaluation. Reads using Cassandra are expensive. Each link
in the graph would probably require a read transaction. I have never used a
graph db, but I would expect their API will be much more efficient for your
needs. Just something to consider before deciding.
Good luck!

Chris, I believe if the timestamp being written if the same or older it will
not apply the write, but do not quote me on this, test it. In this case, if
the timestamp value does not matter, you could simply always write with a
timestamp of 1.

try this bit...
TTransport transport = new TFramedTransport(new
TSocket(Settings.Instance.Host.Address.ToString(),
Settings.Instance.Host.Port));
TProtocol protocol = new TBinaryProtocol(transport);
Cassandra.Client cassandra = new Cassandra.Client(protocol);

Hello Users,
I am planning a system where both metadata and data will be stored. Usually
it will be small file such as word documents along with some specific data
about the file. Sometimes, there will be a large file, possibly a few
hundred meg - a gig such as video. I have read a lot about su
port it.
