In your schema case, for each client_id you will get a single 'when'
row. Just one. Even when there are multiple rows (clustering keys)

I have a scylla table as shown below:
cqlsh:sampleks> describe table test;
CREATE TABLE test (
client_id int,
when timestamp,
process_ids list,
md text,
PRIMARY KEY (client_id, when) ) WITH CLUSTERING ORDER BY (when DESC)
AND
I have two queries. One that gives me the first page from a cassandra table,
and another one that retrieves the successive pages. The fist one is like :
select * from images_by_user where token(iduser) = token(5) limit 10 allow
filtering;
The successive ones are :
select * from
%.
If it is of the same cause, does that mean I should switch to
SizeTieredCompactionStrategy?

Now a simple CQL query like “select * from event_index limit 1” won’t run
and Cassandra log says

Partition id itself should be chronological say a date. Then you put

Can some body tell me is it possible to to do multiple query on cassandra
like Select * from columnfamily where name='foo' and age ='21' and
timestamp = 'unixtimestamp' ;
Please tell me some guidence for these kind of queries
Thank you
Hello Sri,
As far as I know you can if name and age are part of your partition key and
timestamp is the cluster key e.g.
create table columnfamily (
name varchar,
age varchar,
tstamp timestamp,
partition key((name, age), tstamp)
);
Thanks

Thank you i am able to solve this one.
If i am trying as :
SELECT * FROM CompositeUser WHERE userId='mevivs' LIMIT 100 ALLOW
FILTERING
it works. Somehow got confused by
http://www.datastax.com/docs/1.2/cql_cli/cql/SELECT, which states as :
SELECT select_expression
FROM
Somebody in group, please confirm if it is an issue or that needs rectified
for select syntax.

This is not an issue of Cassandra. In particular
http://cassandra.apache.org/doc/cql3/CQL.html#selectStmt is up to date.
It is an issue of the datastax documentation however. I'll see with them
that this gets resolved.

The reason for the error was that I opened the connection to the database wrong.
I did:
con = cql.connect(host, port, keyspace)
but correct is:
con = cql.connect(host, port, keyspace, cql_version='3.0.0')
Now it works fine. Thanks for reading.
2013/1/24 aaron morton aa...@thelastpickle.com:
I try to access my local cassandra database via python. Therefore I
installed db-api 2.0 and thrift for accessing the database. Opening
and closing a connection works fine. But a simply query is not
working:
The script looks like this:
c = conn.cursor()
c.execute(select * from users;)
to search data based
on some part of string.
Could someone please help me to solve the above issues? Thanks.
