How Terraform reshapes the data engineering experience

The article discusses how Terraform can improve the data engineering experience by reshaping modern data stacks. It explains that a modern data stack consists of various tools for organizing, storing, and transforming data. Traditional ELT/ETL pipeline development faces challenges such as complexity, maintenance, scalability, long development cycles, limited visibility, hard-to-reproduce pipelines, and lack of version control. Terraform by HashiCorp is an open-source project that provides infrastructure-as-code and can implement change management of the modern data stack. The author demonstrates how to use Terraform to create a simple replication pipeline between Postgres and ClickHouse, making it easy to deploy and copy-run with different variable sets.
