How does dbt differ from AWS Glue as a data transformation tool?

dbt handles only the T (Transform) in ETL using SQL and Jinja templating within the data warehouse, while Glue handles end-to-end ETL including extraction, movement, and transformation using PySpark. dbt is the standard for analytics engineering on existing warehouse data; Glue moves and transforms raw data from source systems. Many teams use both: Fivetran or Airbyte for ingestion, then dbt for transformation.

Is Fivetran a better alternative to AWS Glue for data ingestion?

Fivetran focuses exclusively on automated ELT connectors with zero-maintenance pipelines, automatic schema migration, and pre-built transformations. Glue requires custom ETL code for most source integrations. Fivetran costs more per connector but eliminates engineering effort for standard SaaS source integrations (Salesforce, HubSpot, databases). For custom ETL logic, Glue or Dagster is more appropriate.

When should I use Dagster or Prefect instead of AWS Glue?

Choose Dagster or Prefect when you want Python-native pipeline code with testability, version control, and local development. Dagster's software-defined assets model provides data lineage and dependency tracking beyond Glue's ETL job model. Both offer hybrid execution (cloud orchestration with local or custom compute), making them more portable than Glue's AWS-only execution environment.
