try this bit...
TTransport transport = new TFramedTransport(new

Settings.Instance.Host.Port));
TProtocol protocol = new TBinaryProtocol(transport);
Cassandra.Client cassandra = new Cassandra.Client(protocol);

Will take a stab at the answers...1) No, all updates to the same key are consider the same row. 2) Use the get_count Thrift API function, or 'count; in the cassandra-cli The counts is *not* accurate, as that would require locking the db to prevent updates while the pixies counted the rows. 3) Yes,
Thread pools are part of the architecture, take a look at the SEDA paper referenced at the bottom of this page http://wiki.apache.org/cassandra/ArchitectureInternalsThe number of threads in the pool are used to govern the resources available to that part of the processing pipeline. AaronOn 19 Sep,

it doesn't look like you're enabling framed mode. trunk changes
framed to default on.

Hello List,
Knowing this question might be more in the area of thrift then
cassandra, here goes:
I have been trying to do some research in using cassandra as backend for
a system build for .net, but for some reason my client seams to terminat

I am using latest from tr

I suspect that this is a bug, because changing the rpctimeout to bootstrap

Hi Mario,
I'll take a shot at answering a few of these, but mostly at this
point, I'd recommend looking at the available documentation. Start at
http://wiki.apache.org/cassandra/FrontPage.

Thanks again for the replies Jonathan Couple more clarifications
1) Since the sstables are write-once only (append only), does cassandra count
the updates to the same key as a separate row ...i.e does the row count include
even the old/deleted data ?
2) If I need the count of the rows
Hello list,
sorry, i forgot a verb... what i meant is "the complexity of the lookup
of a row or a row+columns".
so: get(key) and get(key, column).
Thanks

Hello list,
what is the complexity of specific row and specific row/column with
sstable files? Is it O(1)? i'm considering the idea of putting a graph
in cassandra's datamodel and i'd like to follow n-length paths in n*O(1).
the idea is to create a column family where i store vertices with thei
15 matches
