The jconsole GUI can be a helpful tool for monitoring caching metrics exposed through JMX. For each node and each column family, you can view your cache hit rate, cache size, and number of hits by expandingorg.apache.cassandra.dbin the MBeans tab. For example: ...
Now that we’ve learned more about the structure of a table and done some data modeling, let’s dive deeper into columns. Columns Acolumnis the most basic unit of data structure inthe Cassandradata model. So far we’ve seen that a column contains a name and a value. We constrain each...
To apply this knowledge, we’ll design the data model for a sample application, which we’ll build over the next several chapters. This will help show how all the parts fit together. Along the way, we’ll use a tool to help us manage our CQL scripts. Conceptual Data Modeling First, ...
1. Overview Data distribution and data modeling in the Cassandra NoSQL database are different from those in a traditional relational database. In this article, we’ll learn how a partition key, composite key, and clustering key form a primary key. We’ll also see how they differ. As a ...
Cassandra is an extraordinary tool for storing and managing large amounts of data across distributed data centers providing continuous availability with no single point of failure, and linear scalability. The advance admin topics of Cassandra and also the entire training contents are in line with ...
