RE: Can I create a counter column family with many rows in 1.1.10?
Ah, I'ts with many columns, not rows. I use this in cql 2-3 create table cnt (key text PRIMARY KEY, y2003 counter, y2004 counter);it says this is not a counter column family, and if I try to use default_validation_class=CounterType,it says this is not a valid keyword.What I'm supposed to type in order to create it?

Correct way to set ByteOrderedPartitioner initial tokens
I have 4 Nodes, and I'd like to store all keys starting with 'a' on node 1, 'b' on 2, and so on.My keys just start with a letter and numbers follow, like 'a150', 'b1','c32000'.I've set the initial tokens to 61ff, 62ff ,63ff, 64ff .This does not seem to be the correct way.Thanks.
How to limit query results like from row 50 to 100
With CQL or an API.
Is there any consolidated literature about Read/Write and Data Consistency in Cassandra ?
Like articles with tests and conclusions about it, and such, and not like the documentation in DataStax, or the Cassandra Books. Thank you.
RE: Is there any consolidated literature about Read/Write and Data Consistency in Cassandra ?
I'm sorry, it's because the mail is returning to me, and I thought it wasn't working. That link is similar to what I asked. I'm searching like, for example, PhD,Dr,Ms dissertationsabout those topics in Cassandra; articles like http://www.cs.cornell.edu/projects/ladis2009/papers/lakshman-ladis2009.pdf, but specific to Read/Write operations and/or data consistency.Thank you.

From: edlinuxg...@gmail.com To: user@cassandra.apache.org Asking the question three times will not help getting it answered faster. Furthermore, I believe no one has answered it because no one understands what your asking. Here is something with tests and conclusions and it is not written by datastax or part of a book on cassandra. http://pbs.cs.berkeley.edu/ On Sat, Feb 16, 2013 at 6:19 PM, Mateus Ferreira e Freitas mateus.ffrei...@hotmail.com wrote: Like articles with tests and conclusions about it, and such, and not like the documentation in DataStax, or the Cassandra Books.
