About:
RethinkDB is an open-source, distributed database designed for building realtime web applications. It features a powerful query language that supports joins, aggregations, and subqueries. Its core innovation is a changefeeds system that pushes query results to applications instantly, eliminating the need for complex polling infrastructure.
Key Features:
  • Realtime data streaming with changefeeds
  • Powerful query language with joins and aggregations
  • Distributed architecture with automatic sharding and replication
  • Flexible JSON document model
  • Easy scalability
Use Cases:
  • Realtime collaborative applications (e.g., collaborative editing)
  • Live dashboards and data visualization
  • Multiplayer online games
  • IoT data processing and monitoring
Alternatives:
  • MongoDB – MongoDB is more widely adopted but requires external tools like Change Streams or polling for realtime features, whereas RethinkDB has realtime push built-in.
  • PostgreSQL – PostgreSQL offers stronger relational guarantees and SQL, but lacks native changefeeds; realtime requires extensions like pg_notify or logical replication.
