If you are looking for a database solution that provides high availability and scalability, Apache Cassandra is the answer. This distributed database supports fault tolerance and data replication over multiple datacenters, making it ideal for mission-critical data. Companies like eBay, Constant Contact, and CERN use Apache Cassandra to store and query massive amounts of data. More than 1500 other companies also use this database to power their data infrastructure.
The Apache Cassandra database server requires a minimum of 2GB of RAM. You also need a minimum of 40 GB of hard drive space. To install Cassandra on Linux, you should run it as a non-root user with sudo privileges. Make sure that you have the Java Development Kit installed, as this contains the compiler and other tools that you need to develop Java programs. After installing Cassandra, run the system to see if the database is up and running.
To install Apache Cassandra, you need two Linux servers in the same network. It may be necessary to install Java on the Ubuntu system, but it usually comes pre-installed. To install Apache Cassandra on Ubuntu, you need to add the corresponding repository to your system’s sources. Then, install the latest major version 4.0 series from the repository. This version contains the latest bug fixes and new features.
Cassandra models and distributes data. It handles data addition and deletion. The update operation specifies values for specific columns, while the rest should maintain their previous values. To add columns to the tables, applications can dynamically run alter table commands. This ensures data integrity. The data consistency is also deterministic. When your application runs queries, it will be able to handle mutations without issue. In order to run Cassandra on your application, you must specify the scalability and data integrity requirements for your environment.
Apache Cassandra is a free open-source NoSQL distributed database that was originally developed by Facebook. Because of its distributed architecture, there is no single point of failure. Apache Cassandra is ideal for applications with massive active data sets. Founded by Facebook, Apache Cassandra is the choice of many famous companies and organizations. It runs on Linux systems and is accessible using command-line tools.
Cassandra is scalable, which means it can handle large amounts of data. With its masterless architecture, it supports large amounts of data, and its ability to scale out is easy. Cassandra scales out as your application grows. You can easily add more machines, and your database will continue to scale out without requiring major changes. Its high-throughput architecture and zero copy sharding allow you to scale up without worrying about your data.
