Data Infrastructure with Apache Cassandra E-Learning Training 

In de Data Infrastructure with Apache Cassandra LearningKit leer je werken met Apache Cassandra, een krachtige en schaalbare NoSQL-database die wordt gebruikt in data-intensieve omgevingen.

Onderwerpen:

Introductie Apache Cassandra

• Installatie en configuratie met Docker
• Opzetten en beheren van Cassandra Clusters
• Gebruik van de nodetool utility om clusters te inspecteren en beheren
• Het gebruik van datacenters in Cassandra

Cassandra Query Language (CQL)

• Organiseren van tabellen in keyspaces
• Specificeren van replicatiestrategieën en configuraties
• Tabellen maken, data invoegen en updaten
• Werken met CSV- en JSON-gegevens

Geavanceerde Cassandra-technieken

• Tabelpartitionering en clustering van sleutelkolommen
• Uitvoeren van aggregaties op gegevens
• Gebruik van user-defined functions (UDF’s)

Deze training biedt een solide basis om Cassandra effectief in te zetten voor data-infrastructuurprojecten in moderne, gedistribueerde IT-omgevingen.

Deze LearningKit met meer dan 7 leeruren is verdeeld in drie sporen:

Demo Data Infrastructure with Apache Cassandra Training

Cursusinhoud

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.
