This doesn’t seem like a reasonable use case for Cassandra. I mean, it’s not a typical “database” use case. -- Jack Krupansky From: Philo Yang Sent: Thursday, July 31, 2014 1:44 PM To: user@cassandra.apache.org Subject: select many rows one time or select many times? Hi all, I have a cluste

Authentication for Mx4j

Does anyone know how to enable basic authentication of MX4J with Cassandra? Mx4j supports it but not sure how to pass the variables to enable it. I was able to set the listen address and port for the http server, but can't get authentication to work. Rahul Neelakantan

AW: Migration from Cassandra 1.2.5 to Cassandra 2.0.8 with changed partitioner settings

Well, we ran StorageService.bulkLoad via JMX. According to http://www.datastax.com/dev/blog/bulk-loading this should have the same effect and can be done on the same machine: "Because the sstableloader uses gossip to communicate with other nodes, if launched on the same machine that a given Cas

Re: `system` keyspace replication

Hi Jens, The system keyspace is configured with LocalStrategy, this strategy only stores data on the the local node. This strategy is reserved for internal use only and is used for other things such as SecondaryIndexes. You cannot change the replication factor of the 'system' keyspace. If you att

`system` keyspace replication

Hi, Datastax has a documentation page about configuring replication[1]. It mentions a couple of system keyspaces that they recommend increasing replication for. However, it does not mention the `system` keyspace. Question: Is it recommended to increase replication factor for the `system` keyspace

You said you tried restoring a snapshot via bulk loader, did you actually run sstableloader? Rahul Neelakantan > On Jul 31, 2014, at 2:54 AM, tsi wrote: > > Well, the new Cassandra cluster is already setup with the different > partitioner settings and there are already other applications runni
