​​Newt DB, the amphibious database.

- In #python: enjoy the ease of working with your data as ordinary objects in memory.
- Data are moved in and out of memory as needed, so databases can be as large as needed.
- In Postgres: index and search your data using PostgreSQL, from within your application and externally.
- Within your application, search results may be returned as application objects, or as data, depending on your needs.
- Transactional and built on mature technology for reliability.
