Controlling Dag Logic

Nu bijgewerkt naar Apache Airflow 3.1.6 - Gegevens volgens een schema leveren kan handmatig en omslachtig zijn. Je schrijft scripts, voegt complexe cron-taken toe en probeert op allerlei manieren te voldoen aan steeds veranderende eisen—en samenwerken met teamgenoten maakt het nóg lastiger om alles te beheren. Apache Airflow neemt je deze zorg uit handen door planning, foutafhandeling en rapportage aan je workflows toe te voegen. In deze cursus leer je de basis van Apache Airflow en hoe je complexe data-engineeringpijplijnen in productie implementeert. Je leert ook hoe je Directed Acyclic Graphs (Dags) gebruikt, data-engineeringworkflows automatiseert en data-engineeringtaken eenvoudig en herhaalbaar uitvoert—zodat je het overzicht bewaart.

Intermediate Python

Introduction to Shell

Leer workflows voor data-engineering te plannen met Airflow en Python voor planning en foutafhandeling.
