Re: Advice for asymmetric reporting cluster architecture

Yes, you can have all your normal data centers with DSE configured for real-time data access and then have a data center that shares the same data but has DSE Search (Solr indexing) enabled. Your Cassandra data will get replicated to the Search data center and then indexed there and only there.

Would we have data corruption if we bootstrapped 10 nodes at once?

We just migrated from a 30 node cluster to a 45 node cluster. (so 15 new nodes) By default we have auto_boostrap = false so we just push our config to the cluster, the cassandra daemons restart, and they're not cluster members and are the only nodes in the cluster. Anyway. While I was about

I hadn't considered it because I didn't think it could be configured just for a single data center; can it? On Oct 17, 2015 8:50 AM, "Jack Krupansky" wrote: > Did you consider DSE Search in a DC? > > -- Jack Krupansky > > On Sat, Oct 17, 2015 at 11:30 AM, Mark Lewis

Re: reiserfs - DirectoryNotEmptyException

My advice is to not even consider anything else or make any other changes to your architecture until you get onto a modern and maintained filesystem. VERY VERY VERY few people are deploying anything on ReiserFS so you're going to be the first group encountering any problems. On Thu, Oct 15, 2015

Advice for asymmetric reporting cluster architecture

I've got an existing C* cluster spread across three data centers, and I'm wrestling with how to add some support for ad-hoc user reporting against (ideally) near real-time data. The type of reports I want to support basically boil down to allowing the user to select a single highly-denormalized

Read query taking a long time

Hi, I've read all I could find on how cassandra works, I'm still wondering why the following query takes more than 5s to return on a simple (and modest) 3 nodes cassandra 2.1.9 cluster: SELECT sequence_nr, used FROM messages WHERE persistence_id = 'session-SW' AND partition_nr = 0; The
