The record

Product: Bonobo is a lightweight ETL framework for Python 3.5+ that builds data transformation pipelines from Python primitives and runs them in parallel.
Data flow: Bonobo processes data as streams of independent rows, with each node handling one line at a time while nodes run in parallel.
Graph model: Callable or iterable Python objects can be connected into directed graphs, which Bonobo can visualize and execute.
Built-in formats: The site lists built-in extractors and writers for CSV, JSON, XML, and XLS formats.
Transformations: Transformations can be plain Python or provided transformation classes, and the site describes them as small, scoped units intended to improve testability and maintenance.
SQL integration: The Bonobo-SQLAlchemy extension adds capabilities for working with SQL databases and is installed with the sqlalchemy extra.
Notebook support: Bonobo can detect when it is running in a Jupyter Notebook and display live job status with an HTML widget.
Docker integration: The Bonobo-Docker extension can run a local ETL job in a Docker container with the bonobo runc command.
Docker limitation: The Docker extension page says it does not support running Docker inside a Docker container.
Inputs and outputs: The site says Bonobo can read from HTTP REST/SOAP APIs, filesystems, storage services, and SQL or NoSQL databases, and read or write formats including CSV, JSON, XML, Excel, and Pickle.
Security and warranty: The site describes Bonobo as open-source software provided without any guarantee and says its code and surrounding materials are provided as-is.
Support: The project invites feedback through Slack discussions and GitHub issues and provides a contact email on its site.
Intended user: The site says users who know Python can get started in 10 minutes and presents Bonobo as a toolkit for building ETL jobs.
