Data Infrastructure with Apache Cassandra E-Learning

In the Data Infrastructure with Apache Cassandra LearningKIT, you will explore Apache Cassandra, create Cassandra Clusters, and the Cassandra Query Language. You will explore installing Cassandra and making it available with Docker, creating Cassandra clusters and inspecting them using nodetool utility, and leveraging the data center in Cassandra.

You will also learn Cassandra Query Language to organize tables into keyspaces, specify replication strategy, and configurations, create tables, and insert and update data. You will also learn to work with CSV and JSON data, table partitioning and clustering key columns, and also performing aggregations on the data, and leveraging user-defined functions.

This LearningKit with more than 7 hours of learning is divided into three tracks:

Course content

Track 1: Intro to Data Infrastructure

In this track, the focus will be on data infrastructure in an organization, data mesh architecture, data tools, messaging platforms, and data stores.
Courses (½ hour +):

Setting up the Data Infrastructure in an Organization

Course: 46 Minutes

• Course Overview
• Data Infrastructure in an Organization
• Data Mesh Architecture
• Tools for Data Management
• Messaging Platforms
• Data Stores
• Course Summary

Track 2: Apache Cassandra

In this track, the focus will be on working with Apache Cassandra. Apache Cassandra is a decentralized, distributed, wide-column store that provides great performance at petabyte-scale data for specific types of data and operations. Cassandra is great for data that can be accessed via unique keys and where each row has potentially very different column attributes.
