You can use the "spark.cassandra.connection.local_dc" to restrict the query
to a single data center. It might just be that you can't access the remote
DC from the IP address returned internally when the client attempts to
discover ring topology.

Hi all,
I'd appreciate some help with a Cassandra 2.1.2 issue I'm experiencing. I'm
running a query which looks like this:
CREATE TABLE single_row_fetch (id uuid PRIMARY KEY, data text)
SELECT data FROM single_row_fetch WHERE id = ?
When writing test data into this table, I disabled compaction.

Hi,
I have a cassandra cluster of 3 nodes holding around 300 million rows
of items. I have a replication factor of 3 with read/write consistency as
Quorum. I want to scan all rows of database to generate sum of items having
value "available" in column name state and value "batch1" in column na
I am sorry, not sure if I will be able to help you. I am not familiar with
super columns, I would tell you to try to get rid of them as soon as possible.
Maybe someone else in the list can help you.
Anyway, it really seems you have a cell with a very large amount of data and
the request might be
Hello
I am running 1.2.19

Indeed, I thought something odd could be happening to your cluster, but it
seems it's working fine but the request is taking too long to complete.
I noticed from your cfstats the read count was about 10 in the first CF and in
the second one it was about 1000... Would you be doing much more read

Yulian,
Maybe other people have other clues, but I think if you could monitor the
behavior in tpstats after activity "Seeking to partition beginning in data
file" it could help to find the problem. Which type of thread is getting stuck?

Hi Asit,While I haven't used stratio's lucene indexing, a few points on the
datastax .net connector:
i) It got a major revamp last year. I'm assuming you're using the latest
one?ii) Are prepared statements actually being reused many times? If not,
perhaps the overhead isn't worth it. Prepared st
