RethinkDB

About RethinkDB

An open-source document database designed for building real-time web applications. RethinkDB pushes query results to applications in real-time, eliminating the need for polling and making it ideal for collaborative apps and live dashboards.

Key Features

• 1Real-time database that pushes JSON query results to clients on data change
• 2ReQL query language — chainable Python, JavaScript, or Ruby API
• 3Changefeeds subscribe to table changes and receive updates as they happen
• 4Automatic sharding and replication with a visual admin dashboard
• 5Joins, sub-queries, and aggregations on JSON document collections

How Python Data Engineers Use RethinkDB

Python data engineers use `rethinkdb` (the Python driver) to build real-time data feeds — subscribing to a changefeed on a table and forwarding inserts and updates to downstream consumers via WebSockets or a message queue. This push model eliminates polling loops in event-driven ingestion architectures.
