## What it is
Pentaho Data Integration (Kettle) is an open-source ETL application for designing and running data extraction, transformation, and loading pipelines. It provides a graphical designer (Spoon), a Java execution engine, and a plugin architecture for connecting to many data sources.

## Use cases
- extract transform and load data between databases
- migrate data from one database to another
- build scheduled data pipelines
- cleanse and transform csv files into a data warehouse
- integrate data from multiple sources
- run batch data jobs on a schedule
- visual etl designer for data integration

## When to choose
- you need a mature GUI-based ETL tool with hundreds of built-in connectors
- you want to build data pipelines without writing code
- you need a self-hosted, open-source data integration platform

## When to avoid
- you prefer code-first pipeline frameworks like Airflow or dbt
- you need a lightweight CLI-only tool
- your license requirements demand a standard permissive open-source license
