I get a lot of TExceptions
What are the exceptions ?
In general counters are slower than writes, but that does not lead them to fail
like that.
Check the logs for errors and/or messages from the GCInspector saying the
garbage collection is going on.

SystemManager.create_column_family().

cassandra 1.2.0
Is it a bug in 1.2.0 ?
While I can't speak to this specific issue, 1.2.0 has meaningful known
issues. I suggest upgrade to 1.2.3(/4) ASAP.

Is the following supposed to work ?

If you have one column in the table that is not part of the primary key and is
a counter, then all columns that are not part of the primary key must also be a
counter.

Note that CQL 3 in 1.1 is compatible with CQL 3 in 1.2. Also you do not have
to use CQL 3, you can still use the cassandra-cli to create CF's.
The syntax you use to populate it depends on the client you are using.

There's nothing that will do it automatically. You need to increment it
yourself.

Can u give an example of create column family with counter column in it.
Please reply

*create column family MyCounterColumnFamily with
default_validation_class=CounterColumnType and
key_validation_class=UTF8Type and comparator=UTF8Type;*
There you go! Keys must be utf8, as well as the column names. Of course you
can change those validators.

the counter column family works synonymous as 'auto increment' in other
databases rite?
I mean we have a column of type integer which increments with every insert.
Am i goin the rite way??

You should end up with the interface/gen-php/
