Hi All,
Can any one suggest me how to retrieve the result count after multiple
filtration operations performed on multiple column families something
similar like join query result count in normal RDBMS. I guess its not
possible in Cassandra, still asking? Or any other alternative to do the same
You can check Astyanax API
https://github.com/Netflix/astyanax/blob/5c05d118e22eef541a7a201adf7c1c610da13f5b/src/test/java/com/netflix/astyanax/thrift/ThrifeKeyspaceImplTest.java
There are some counter column example which will surely help you.
There should be at least one "=" (equals) in the WHERE case on key or
secondary index column, this is the Cassandra limitation.
Hey Rajesh,
For better response put this question in Datastax support forum *
http://www.datastax.com/support-forums/forum/datastax-enterprise*

Abhijit
Perform these steps on each node:
Start the Cassandra-cli connected to your node.
Run the following:
1. use system;
2. set LocationInfo[utf8('L')][utf8('ClusterName')]=utf8('Brisk
Cluster');
3. exit;
4. Run nodetool flush on this node.
5. Update the cassandra.yaml file for the c
have you flushed the node using NODETOOL after renaming the cluster?
If you have used the above commands then i guess problem lies in this step.
[default@system] set LocationInfo[utf8('L')][utf8('*Test
Cluster*')]=utf8('Jokefire
Cluster');
It should be like this: set LocationInfo[utf8('L')][utf8('Cluster
Name')]=utf8('Jokefire Cluster');
Hey Tim,
Can you repeat these steps as given below? I guess now you are missing
step no 6.
Start the Cassandra-cli connected to your node.
Run the following:
1. use system;
2. set LocationInfo[utf8('L')][utf8('ClusterName')]=utf8('Brisk
Cluster');
3. exit;
4. Run nodetool flush
using community version.

personally found it quite abnormal, so thought of posting this thing in
forum.

I don't know the exact value on a column, but I want to do a partial
matching to know all available values that matches.
I want to do similar kind of operation that LIKE operator in SQL do.
Any help is highly appreciated.

Hi All,
i am facing problem while setting up my database. The error under mentioned
is reflected every time i try to
setup the DB. Unable to understand why these are occurring? though
previously it was working fine, i guess
it is some connection related issues.
UnknownException: [host=192.168.2.1
Hi All,
Right now i am trying to use Fluent Cassandra API for development in asp.net
.
For the same purpose i have downloaded the same source from github. But
every time i add a new reference *fluentcassandra.dll*, i am unable to use
it
in my code. I am not able figure it out why this is happening
U can use Astyanax API. These sort minor issues are resolved in that API.

Hi,
I have downloaded the CQL driver provided by Datastax using
com.datastax.cassandra
cassandra-driver-core
1.0.0-beta2
Then tried a sample program to connect to the cluster
Cluster cluster = Cluster.builder()
.addContactPoints
@Gabriel, @Wright: thanks, such a silly of me.

You have the collection attributeNames, just iterate it
Iterator it = result.iterator();
while(it.hasNext()){
Row row = it.next();
