(I think the thread count was reduced in the past before the C* server
upgrade and we still had problems, but I could always try again).
Any ideas/suggestions are greatly appreciated.

Hi,
We are running Cassandra 2.1.14 on an IBM AIX cluster using IBM Java 7
(1.7.1.64). I am having problems adding new nodes to the cluster. I am
seeing the following exception. It appears like the new node is
getting stuck trying to send the magic number on the first streaming

I have a question about CQL memory usage. I am currently using 1.2.9.
If I have a Cassandra table like this (created using Astyanax API):
CREATE TABLE table_name (
key text,
column1 text,
value blob,
PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE;
and I run a query like this:
OK, thanks for the information.

Hello Edward,
I am curious - What about triggering on a TTL timeout delete (something I
am most interested in doing - perhaps it doesn't make sense?)? Would you
say that is something the user should implement themselves? Would you see
intravert being able to do something with this at some later po
Hi Renato,
Are you sure that you don't have two copies of guava in your classpath? I
don't have this problem (I was using both Hector and Astyanax for a while
-> now transitioned completely to Astyanax).
Probably the most problematic part of using the datastax or astyanax
clients is that they bot

Hello,
If I have a cql3 table like this (I don't have a table with this data -
this is just for example):
create table (
surname text,
city text,
country text,
event_id timeuuid,
data text,
PRIMARY KEY ((surname, city, country),event_id));

Hello,
I have been playing with map literals in CQL3 queries. I see that
single-quotes work:
{'foo':'bar'}
but double-quotes do not:
{"foo":"bar"}
I am curious. Was there a specific reason why it was decided to use
single-quotes?
I ask because double-quotes would make this valid json.
thanks
Hi,
I have a question on if I could do something in Cassandra similar to
what I can do in SQL.
In SQL (e.g. SQL Server), if I have a generated primary key, I can get
the generated primary key
back as a result for the insert statement.
Is it possible to do something similar with CQL (e.g. could I

Hi,
I created a table with the following structure in cqlsh (Cassandra
1.2.3 - cql 3):
CREATE TABLE mytable ( column1 text,
column2 text,
messageId timeuuid,
message blob,
PRIMARY KEY ((column1, column2), messageId));
I can quite happily add values to this table. e.g:
