What is a DAG? To understand what a DAG is, let’s first define some key concepts. In computer science, a graph is a non-linear data structure that consists of nodes and edges. Nodes represent individual entities or objects, while edges connect these nodes and represent relationships or con...
It is a simple table definition, but it carries metadata on board telling the user which database and schema to use: /* models/example/table_a.sql Welcome to your first dbt model! Did you know that you can also configure models directly within SQL files? This will override configurations ...
DAG (Directed Acyclic Graph) in Spark/PySpark is a fundamental concept that plays a crucial role in the Spark execution model. The DAG is “directed” because the operations are executed in a specific order, and “acyclic” because there are no loops or cycles in the execution plan. This m...
A directed acyclic graph (DAG) is a tool for modeling and visualizing complex workflows when task dependencies are important. This type of dependency graph can be used to identify which tasks have to be completed before others can start, which tasks can be performed at the same time, and whi...

Data engineering is a skill that’s been steadily rising in demand over the years. Data engineers work on making raw data usable for further data-driven work by data scientists, data analysts, and all other end users within an organization. Data engineers work with big data tools to manage ...
IOTA Is Not a Blockchain Tangle is a Decentralized Acyclic Graph (DAG), a system of nodes that is not sequential. Thus, each node can be connected to multiple other nodes in a Tangle. However, they are connected only in a particular direction, meaning a node cannot refer back to itself...
