ArkFlow is a newly emerging stream processing engine built using the Rust programming language and the Tokio async runtime. It is designed to deliver high performance and low latency in handling real-time data streams. Key features include support for multiple data sources such as Kafka, MQTT, and HTTP, as well as advanced processing capabilities including SQL query support, JSON processing, Protobuf encoding/decoding, and batch processing. Furthermore, ArkFlow's modular architecture allows users to easily extend functionality by integrating new input, output, and processing components. There is a growing interest in its performance when benchmarked against competitors like Bento.
