Tools/AWS_Glue
AWS Glue
Serverless ETL and data-catalog service — schema discovery, format conversion (e.g. CSV to Parquet), and job orchestration for data lakes. Most-used open-source stack covering the same ground: Apache Airflow (orchestration) + dbt (transformation) + Apache Hive Metastore (catalog); Airbyte is the most-used OSS alternative specifically for the extract/load side Glue also covers. No single OSS tool replaces Glue end-to-end — it's normally a 2-3 tool combination.
