Streaming

Overview

DBCode supports live streaming from databases and message brokers that provide real-time event feeds. When you subscribe to a data source, the data grid switches into streaming mode — incoming events appear as new rows in real time, with a status bar showing the connection state and event count.

Streaming is available for:

Database	Mechanism	Subscribe Target
PostgreSQL	LISTEN/NOTIFY	Channels
MongoDB	Change Streams	Collections
Redis	Pub/Sub	Channels
SurrealDB	LIVE SELECT	Tables
Apache Kafka	Consumer Groups	Topics
RabbitMQ	AMQP Consumers	Queues

How to Subscribe

Right-click on a supported item in the connection explorer and select Subscribe from the context menu. The data grid opens in streaming mode with a broadcast icon indicating an active stream.

For databases that support it, you can also start a stream from the query editor:

• PostgreSQL: LISTEN channel_name;
• MongoDB: db.collectionName.watch()
• Redis: SUBSCRIBE channel_name
• SurrealDB: LIVE SELECT * FROM table_name;

Streaming Grid

While a stream is active, the data grid displays:

• Status bar: Shows the stream source, event count, and elapsed time
• Stop button: Click to end the stream and return the grid to a normal state
• Live rows: New events appear at the top of the grid as they arrive

Each event row includes metadata such as the event type (create, update, delete, message) and a timestamp.

Requirements

• PostgreSQL: Any PostgreSQL server supports LISTEN/NOTIFY
• MongoDB: Requires a replica set or sharded cluster. Standalone MongoDB servers do not support Change Streams
• Redis: Any Redis server supports Pub/Sub
• SurrealDB: Any SurrealDB instance (WebSocket connection required for live queries)
• Apache Kafka: Any Kafka broker
• RabbitMQ: Any RabbitMQ broker with the management plugin enabled

Availability

Live Streaming is a Pro feature. See Pricing for details.
