Its reliability, along with its high fault tolerance, has earned the reputation information technology holds today. The DB Engine Ranking puts Cassandra at the top of their wide column shop ranking.

In this tutorial, you'll acquire how to fix up Apache Cassandra, 1 of the best NoSQL databases systems that is both gratuitous and open up-source, which offers high linear scalability, forth with depression latency operability. It was originally conceived to support the inbox search characteristic on Facebook and has since improved until information technology was hailed as the most time-efficient and scalable distribution database.

Step 1: Install Oracle Coffee

Then, run the command below to install OpenJDK 14:

$ sudo apt install openjdk-xiv-jdk

OpenJDK 14 should launch automatically upon install. To verify the install, type:

This should be displayed in the following output:

With Java installed, yous can download the latest version of Apache Cassandra from its official website. Withal, in this demonstration, nosotros'll utilise the official Apache repository past adding it to the local software repository.

Step 2: Installing Apache Cassandra

The post-obit steps prove the details on how to download Apache Cassandra by calculation its official repository. This particular method might prove useful in cases where yous're unable to download it from the official website.

The method used in this tutorial start added the Apache repository to the Ubuntu software repo, then installed the database.

What makes Cassandra, in particular, a stand up out compared to other database systems is the high-volume information capacity that it offers, too as its extremely low latency operations. The fact that then many large conglomerates utilise this database system, including Apple, Facebook, Instagram, Spotify, Twitter, eBay, and Netflix, speaks to its utility as a reliable information direction platform.
