Any Cassandra deployment being worked with on a long term basis needs some sort of monitoring solution. Monitoring is extremely useful in the process of diagnosing problems with a cluster. It also helps ensure optimal performance in production systems. There are many ways of monitoring Cassandra clusters, but they can broadly be split into two groups. The first group relies on Cassandra’s JMX integration since Cassandra is a Java application based on JVM. The other group is based on the analysis of Cassandra logs. We have a previous discussion of log-based monitoring that can be found here.Continue reading
Datastax Enterprise Graph (DSE Graph) is a NoSQL database tool that is optimized for storing objects and their relationships. It is a distributed database, just like Cassandra, and has many of the same advantages. It can scale to handle massive amounts of data, is optimized for high-speed transactions, and built for high reliability, just like Cassandra. DataStax enterprise graph specifically, also comes with access to other DataStax enterprise features, like DSE Search capabilities and security features.Continue reading
In this blog post, we will introduce Spark, a unified analytics engine for large-scale data processing, and discuss how to use it to do SQL on a NoSQL database like Cassandra. We will also give you a quick demo to show how you can quickly test it out yourself. This is Part 2 of our series on “Doing SQL and Reporting on Apache Cassandra with Open Source Tools”, and part 1 is linked below. Also, be on the lookout for Parts 3 and 4 coming soon!Continue reading
In Cassandra Lunch #15, we discuss Cassandra Backup / Restoration. We discuss disaster avoidance, disaster recovery, and different tools that can be used for backup and restoration of your Cassandra data. Also, we discuss an example scenario of how someone has set up multi-node clusters and how they go about data backup and restoration.Continue reading
