Thanks Mikhail. I switched to 2.0.3 and the problem is still there, I will open an issue with a test case on it. I have not tested 1.2.12, but I assume that will have the same problem. Shahryar On Mon, Nov 25, 2013 at 5:57 PM, Shahryar Sedghi wrote: > I did some test and apparently

Prepare is 100 to 200 times slower after migration to 1.2.11

Hi I have migrated my DEV environment from 1.2.8 to 1.2.11 to finally move to 2.0.2, and prepare is 100 to 200 times slower, something that was sub millisecond now is 150 ms. Other CQL operations are normal. I am nor planning to move to 2,0.2 until I fix this. I do not see any warn or error in

Commit log and data separation on SSD

This my first SSD experience. With normal disks we separate commit log from data. We have 2 SSDs dedicated to Cassandra I was wondering if we gain a better performance if we put commit log in one and data in another, or just use raid 0 to have both SSDs combined. Thanks in Advance Shahryar

CQL update and TTL

Apparently when I update a column using CQL that already has a TTL, it resets the TTL to null, so if there was already a TTL for all columns that I inserted part of a composite column set, this specific column that I updated will not expire while the others are are getting expired. Is it how it is

Re: Why do Datastax docs recommend Java 6?

I use IBM JVM 7, it is free, and for VMs over 8 GB it has a garbage collection policy that makes it almost pause-less. We also use some security libraries that eliminates use of other libs that you need for Oracle. On Thu, Apr 4, 2013 at 12:59 AM, Edward Capriolo wrote: > Hey guys. what gives!

Cassandra 1.2, wide row and secondary index question

CQL 3 in Cassandra 1.2 does not allow order by when it is a wide row and a column with secondary index is used in a where clause which makes sense. So the question is: I have a test table like this: CREATE TABLE test( interval int, id uuid, severity int, PRIMARY KEY (interval

Hi I am trying to test my application that runs with JDBC, CQL 3 with Cassandra 1.2. After getting many weird errors and downgrading from JDBC to thrift, I realized the thrift on Cassandra 1.2 has issues with wide rows. If I define the table as: CREATE TABLE test(interval int,id text, body text,

I use JDBC with Cassandra 1.1 with CQL 3. I tried both Hector and Thrift and JDBC is much easier to code, I never tried Astyanax. Application servers have built-in connection pooling support for JDBC, but do not provide fail over to other machines, you need to do it at the application level. Ano
