(I think the thread count was reduced in the past before the C* server

Any ideas/suggestions are greatly appreciated.

are there some additional caveats that I
should be aware of for 'IN' query performance (e.g. ordering of 'IN'
query entries, closeness of 'IN' query values in the SSTable etc.)?
thanks in advance,

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
socket...whilst
Hello,
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,
Say I have time series data for a table like this:
CREATE TABLE mytimeseries (
pk_part1 text,
partition bigint, e.g. partition per day or per hour
pk_part2 text, this is part of the partition key so I can
split write load
message_id timeuuid,
secondary_key1 text,
what feature you suggesting. Columns can already have
a
ttl. Are you speaking of a ttl column that could delete something beside
itself.
That does not sound easy because a ttl comment is dorment until read or
compacted.

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
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

Is there something I am missing here or should I open a new ticket?
Yes please.

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));
there is no way of (easily)
* from yourtable where surname=blah and city=blah blah and
country in (country1, country2)
Hope that helps

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.

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
