Re: Hbase vs Cassandra

Hi Ajay, You won't be able to get unbiased opinion here easily. You'll need to try and see how each works for your use case. We use HBase for the SPM backend and it has worked well for us - it's stable, handles billions and billions of rows (I lost track of the actual number many moons ago) and

Re: opscenter with community cassandra

Hi Tim, We have happy SPM for Cassandra users who are using SPM for monitoring, alerting, and anomaly detection for their Cassandra clusters. SPM agents phone home by definition if you are using the Cloud version. The On Premise / AWS AMI versions do not phone home. See: http://sematext.com/spm

Re: High cpu usage & segfaulting

Hi Stan, Put some monitoring on this. The first thing I think of when I hear "chewing up CPU" for Java apps is GC. In SPM you can easily see individual JVM memory pools and see if any of them are at (close to) 100%. You can typically correlate that to increased GC tim

Programmatic Cassandra version detection/extraction

Hi, Is there a way to detect which version of Cassandra one is running? Is there an API for that, or a constant with this value, or maybe an MBean or some other way to get to this info? Here's the use case: SPM monitors Cassandra , but Cassandra MBeans and metrics have o

Cassandra Wiki Immutable?

Hi, What is the state of Cassandra Wiki -- http://wiki.apache.org/cassandra ? I tried to update a few pages, but it looks like pages are immutable. Do I need to have my Wiki username (OtisGospodnetic) added to some ACL? Thanks, Otis -- Performance Monitoring * Log Analytics * Search Analytics S

ANN: All Cassandra Resources Searchable

Hi, We did this a while back, but never notified Cassandra community - we're indexing all Apache Cassandra resources - user/dev lists, wiki, website, JIRA, source code, and javadoc over at http://search-hadoop.com/cassandra . Some Apache projects, like Hadoop - http://hadoop.apache.org/ and HBase
