The new GNOME version includes a dark theme that follows a standard of colors that makes more sense and is more well-respected by desktop programmes. Currently, Cassandra and MongoDB are two of the most widely used NoSQL databases. Cassandra is intended to handle massive amounts of data on distributed systems in a scalable, fail-safe manner (clusters).
Apache HBase is a NoSQL database that is written in Java. It has many similarities to CouchDB and MongoDB, both of which are written in C++. Cassandra Query Language (CQL), a SQL-like query language, has been available since version 0.8. This means that you can use it to access the data stored in Cassandra without having to learn the underlying codebase. The steps to install Cassandra on Ubuntu 22.04 LTS Jammy are as follows:
- Open a terminal window and type the following command: sudo apt-get update && sudo apt-get install cassandra
- Type the following command to start Cassandra: cassandra start ..

Final Words
If you’re looking for a relational database that can handle large amounts of data, Cassandra may be the right choice for you. It’s written in Java and RubyGems, so it should work on most UNIX-like operating systems, including Mac OS X and Linux. Additionally, experienced developers should take a closer look at the structure and data model of Cassandra because there are some similarities in the data model in addition to the emergence of fundamentally new terms as well as some familiar terms that, while present in Cassandra, have a completely different meaning. ..
