A lightweight real-time big data streaming engine built on Akka for high-throughput, low-latency data processing.
Gearpump is a lightweight real-time big data streaming engine built on the Akka framework. It processes continuous data streams with high throughput and low latency, solving the need for scalable, fault-tolerant stream processing in distributed environments. The engine models streaming within Akka's actor hierarchy for efficient message handling and resilience.
Data engineers and developers building real-time streaming applications that require high-performance, low-latency processing of large-scale data streams. It suits teams familiar with Akka and Scala seeking a lightweight alternative to heavier streaming frameworks.
Developers choose Gearpump for its simplicity, high performance, and Akka-based architecture, which offers better concurrency and fault tolerance compared to traditional streaming engines. Its lightweight design reduces overhead while delivering near 18 million messages/second throughput.
Lightweight real-time big data streaming engine over Akka
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Benchmarks demonstrate processing near 18 million messages/second with 8ms latency on a 4-node cluster, as highlighted in the performance report linked in the README.
Models streaming within Akka's actor hierarchy, leveraging efficient message passing and built-in fault tolerance for concurrency and resilience, as described in the architecture.
Inspired by gear pump mechanics, it emphasizes a minimalistic core that reduces overhead while maintaining power, aligning with its philosophy of simplicity.
Supports distributed deployment across multiple nodes for horizontal scaling, enabling large-scale data pipelines in real-time streaming applications.
Requires proficiency in Scala and Akka's actor model, which can be a significant barrier for teams not already invested in these technologies, limiting accessibility.
As a lightweight engine, it lacks the extensive pre-built connectors and community tools found in mature frameworks like Apache Flink, potentially increasing development effort.
Building from source requires sbt, specific Scala versions (e.g., 2.12), and proxy configurations for network issues, as noted in the build instructions, complicating initial deployment.
