Console’s review

· Reviewed by David Mytton

What we like

Takes inputs (MQTT, Kafka, HTTP, database queries, Nats), then processes the data (JSON, SQL, batch, VRL), and sends the result to an output (Kafka, MQTT, HTTP, stdout, Nats). Can buffer in memory to apply backpressure. Uses the Rust Tokio async runtime and builds to a single binary for deployment.

Tradeoffs

Fewer connectors compared to other stream processors like Bento. Missing databases as output options.
